re: Sleep Apnea...Have anyone of you had this?

My insurance pays to replace my mask every six months so I replace my mask, hose and headgear about that often. I have been on a CPAP machine for about 15 years now and it has made a world of difference. If I have to travel and forget to bring my CPAP or if no electricity is available and I sleep without my mask I feel like shite the next day. Even one night makes a difference to me. But I was fat 6:0 255 lbs when I was diagnosed. I am now at 165 and the machine is still very important for my sleep even though I am a bit under where my oncologist wants me. He would like me to be between 180 and 200 lbs. I have been having trouble gaining weight because the chemo has killed my taste and appetite so I just eat because I need calories not for any enjoyment in fact eating has become a chore and it is easier not to eat than to get up and fix something
