Well i must say that i have a little different experience then the rest of you. I am currently 335 pounds and have been diagnosed with sleep apnea. I use a cpap machine set at 19cm of water pressure, which really bothers me. i have been using the cpap for about two years now and it really bothers me. I use a full face mask becuase i do not breath out of my nose. I have been getting side effects such as my teeth bleeding and hurting when i wake up. My sleep apnea is the reason why i am attempting to get the lab band surgery. I would like to get off of it, but if not then i would at least like to lower the pressure substantially. Becuae my need is so high (19) it is critical that i lose weight, otherwise i could be heading towards a tracheostomy in the near future. Has anyone had any experiences like mine. Are you guys getting the surgery to get off the cpap? I was told by my doctor that it would drastically help me. I am just trying to see if i will get financed for it .
