Burping??

When I went to my last follow up with my sleep Dr he gave me a nose mask to try to use. I am a mouth breather, but am having trouble finding a full mask that fits without leaking so he thought maybe I could train myself to sleep with my mouth closed or use a chin strap. I have been doing ok with just the mask. I dont wake up with an open mouth. I cant even open my mouth when awake because of the rush of air i can feel in my mouth/throat when I open it I feel like I am sufficating.  However, i notice I wake up at times and have to burp several times as if i was gulping air. Has anyone else had this issue? Does that mean I am opening my mouth in my sleep and just dont know it?

Thanks for the info.

When you first get the machine, you swallow a lot of air until your body gets used to it. This will pass in about a month or so. Stick with it, it will be worth it. Sea

I have been on the machine since January this only started when i switched from a full face mask to a nasal pillow.

But My Dr has called in for a chin strap so hopfully that will help.

Thanks.

I have just started this burping in the middle of the night.  I have been using nasal plugs however the style of my hair causes my mask to move.
