Finally Refreshing Sleep and UARS relief!
I have long suspected I have a mild form of sleep apnea after a home sleep study a few years ago revealed “upper airway resistance syndrome” or UARS, But when I did the in-lab study my oxygen levels were normal, which is common in UARS. I have long suspected something was wrong because I am always sleepy and never feel refreshed no matter how long I sleep. After research, it turns out UARS doesn’t usually cause oxygen levels to drop, as the airways narrow but never fully constrict, but your body still wakes up partially, called micro arousals, and these can cause the same unrefreshed sleep and daytime fatigue as the more severe sleep apnea since your body exits deep restorative sleep every time your airways narrow, even without them shutting. I’m currently working with a sleep doctor to get to the bottom of it, but in the meanwhile decided to see if I could test my theory by buying this device, which moves the lower jaw slightly forward, similar to a mandibular advancement device. I noticed a dramatic difference after night one that has persisted. I started with band 3, which seems perfect for me, and that night I slept 9.5 hours instead of the 11-13 hours I normally do just to be able to barely function, AND I felt rested. The next night I slept 9 hours then 8, now I’m averaging 7-8 hours of sleep each night feeling FARRR more rested than I ever did on 11-13 hours previously. This has been a miracle and given me back so much time and quality of life. It did take a few trials of molding to get the fit right and stop any pieces from cutting the inside of my lip by trimming off the excess material, but after that and some dental soreness with my back teeth the first few nights, I got used to it and no longer have pain. I do wish it was ever so slightly less bulky, as sometimes I do get a slight gag sensation, but I also have a over-sensitive gag reflex from acid reflux which could be part of why. But the device is well-made, durable, comfortable, and well fitted. The instructions are incredibly thorough and helpful for getting started, the company leaves no stone unturned. Overall, I am highly impressed with this device, and customer service is top of the line, downright phenomenal. When I reached out to inquire about replacement bands since mine had stretched a bit after a couple of weeks enough to reduce the effectiveness, customer service was extremely helpful and promptly responsive. The customer service manager, Robert W, said he would send not one but my first THREE replacement bands free of charge with expedited shipping and even sent me complementary sleep patches which contain all natural sleep aid ingredients like magnesium, melatonin, and hops to promote restful sleep, wonderful as a chronic insomniac. That was so above and beyond and truly made me feel valued as a customer. I took my first one tonight, easy to apply, no pill to swallow and I can already feel myself getting sleepy almost within minutes, can’t wait to update this review once I’ve done the patches for a couple of days. This has been a Godsend and just confirms something was going on all along as I had always suspected!

It Works for Me!
The CPAP I’ve been using for 20+ years just wasn’t doing it for me anymore. It became increasingly cumbersome to sleep with, travel with, and the supplies were becoming more expensive with changes in insurance. I stopped wearing it, but my rest suffered and I disturbed my husband’s sleep as well. When I became aware that a mouth guard could be an option, I was intrigued and spent a good deal of time considering reviews. Somnofit-S caught my attention because it is Swiss made (I trust the Swiss for their quality workmanship) and FDA cleared for snoring (although not for sleep apnea because it doesn’t require a prescription).I have used this appliance for 2 weeks and, according to my husband, I am not snoring. I wake up feeling and appearing refreshed. Although the guard feels bulky initially, I got used to it in just a couple of days. It was easy to fit and mold to my mouth after reading the instructions, watching the video and spending a few minutes making minor adjustments pertaining to the choice of straps to use. I may need to remold the bottom to get a better fit (it can be remolded up to 3 times). I cannot yet speak to the durability, but it seems that with proper maintenance it will last the 6-12 months stated on their website.

Snoring is GONE, I am a Customer For Life
Okay, so I NEVER leave reviews, but I really had to for this one. I’ve tried a couple of other mouth guards and HATED them. They were bulky and left me all drooly, and fell out as soon as I fell asleep. But I was finally at the end of my rope, my watch was alerting me to possible apnea, and was feeling exhausted all the time no matter how long I was in bed. Even I could tell I was snoring myself awake when I tried to take a nap in the middle of the day. So I had a discussion with ChatGPT, of all things, which recommended this product. It was twice what I’d spent previously, but I figured it was this or an CPAP machine, and it had a money-back guarantee, so what did I have to lose?I followed the instructions. Watch the video all the way through for sure, it’s full of helpful information. It was cooler in the house, so I should have used the “boil an additional 20 seconds” guide for fitting. I had to redo the top mouthpiece, which made me nervous because you can only redo them three times. But I got what I thought was a good fit, and tried it that night.First night: slept for a couple of hours, then my teeth were hurting, so I took it out.Second night: slept all night, but my teeth were… tender? The next morning. BUT! Holy cow did my sleep apnea chart show a major difference! The thing basically eliminated my snoring. At this point, I didn’t care if it shifted all my teeth, but I was also pretty sure that’s not how it was supposed to work, so since they stress that if you have any trouble, you should contact customer support, I did. On a Sunday. I didn’t expect to hear back for a couple of days, but I did that same day. I got several helpful things to try (go down a size on the straps, redo the molding process), and they said not to worry if I had to mold a few times, they could send replacement molds so I could get it right. This thing has a LOT of ways to adjust, so it really can take a bit of time to figure it out, but I think that’s also why it works for so many people. It’s really well thought out, and the straps can both/either position your jaw and/or just keep your mouth mostly closed, which I think is half the battle for me.Amazing customer service. Definitely reach out to them if you have ANY problems. They were quite responsive and seem to genuinely care. I’ve fiddled with the settings a bit, and think I’m almost there. Really, you’re supposed to use it a couple of hours for a few nights before you sleep to let your jaw adjust, so some of what I’m doing wrong is user error. But knowing that I can NOT snore is too tempting to pass up.As a side effect, my husband, who is a terrible sleeper, got three consecutive days of “perfect sleep” on HIS watch, because “someone” is not tossing and turning next to him due to being snorted awake 90 times a night. So it’s like a two-for-one product!I’ve attached the graph of my sleep disturbances. You can see the last four days, where I started using the mouth guard. This this really is the silver bullet I was looking for. For me, it’s comfortable enough that I can sleep with my mouth closed, lips closed. It does not make me drool at all, but I know that’s not the case for everyone. Seriously, if you’re at all wondering, you really do get what you pay for, and this thing is worth is. It’s valid for many of those health account spending categories, and it comes with a 120-night money-back guarantee. Yes, I don’t know if it’ll work for you, but I definitely know it might, and if you were as tired as I was, that is enough to make it worth a shot.

Adquirí esta guarda para ver si me ayudaba a disminuir los ronquidos, y en mi caso si los disminuyo considerablemente. Utilizo la app de SnoreLab para ver resultados.No es la primera guarda que utilizo que empuja la mandíbula hacia enfrente, pero si la más cómoda ya que trae varios niveles de ajuste mediante unas correas de plástico intercambiables.Les recomiendo ver el video de como moldearla utilizando agua caliente, ya que, si tiene su proceso, pero se puede moldear hasta 3 veces. El precio es elevado, pero me ayuda a dormir mejor…vivo solo y mis ronquidos no molestan a nadie, pero esto hace que no me levante con dolor de garganta en la mañana y tengo menos cansancio durante el día.Les recomiendo tambien utilizar una almohada que eleve bien su cabeza, ya que esto ayuda aun mas a que la lengua no se vaya para atras de la garganta… con almohada delgada me ayudo yo creo en un 50%, con almohada gruesa yo creo un 95%
