Hello cpap users and sufferers I can relate to all the troubles with masks, chin straps etc. I was diagnosed with OSA at 30 but felt like I've always had it. I need help I still struggle with my mouth opening I tried 2 kinds of chinstraps and now I use medical tape. I still find it difficult to get used to this I'm 5'6"and weight 148 so what's my problem? The doctor said it could possibly be tongue base related. I had the UPPP surgery along with having my tonsils removed and septum straighten. What else can help me?
