Hi, all: I am a 31 year old male who was recently diagnosed with severe sleep apnea. I have been on the CPAP for over 3 weeks without much improvement in how I feel. I'm beginning to wonder if my apnea came with CFS or Fibro. All of my problems started in November 2007, when I got a flu that had constant gas and severe positional dizziness with vomiting. During this period, my head suddenly started feeling strange, like it lacked enough oxygen or something. Then the sleep problems began. It took me a while to even get my appetite back, and while I'm doing a little more now, most days are pretty much the same. Here are my symptoms: Sleep related: I often have insomnia or broken sleep. My sleep also does not feel very deep, even though I dream on some nights, yet it's hard to wake up. Feels like I could stay in bed forever. Sometimes have annoying half awake/half asleep periods towards wake up. I feel worse when waking up than when I went to bed. Never really feel fully awake. I don't really sleep during naps. Feel most awake when I'm about to go to bed. Cognitive: Lots of symptoms here. I wake up with my head spacey, foggy, achey, and full - kind of like there is brain damage, but the CAT scan showed no abnormalities. I have lots of trouble concentrating, doing normal activities, my thoughts are dulled (especially in the morning,) and feel mentally dreained. My alertness is dimished. It feels like during the day, I am fighting dozing off or spacing out completely. Head is very sensitive to stress. Ears feel full and bothersome, and my tinnitus bothers me. I don't know why nights are better (still not normal, though.) The cognitive stuff bothers me the most; it is maddening. Body: There are these other symptoms: - bowel problems (stomach gas, bloating, frequent bowel movements and then constipation) - physical fatigue, but the mental fatigue is worse - frequent urination (I do not have an infection) - some hyperventilation and out of breath feelings - some chest pain and heart palpitations - restless legs, especially at night. They often bother me when I try to sleep. - sore and weaker leg muscles - sensitive muscles, but I do not have the frequent pains that many fibro people mention Mood: - high anxiety, irritible, emotionally unstable, have to relax my mind completely to get anything done. Otherwise my cognitive symptoms flare up to an unbearable degree. Also depression, but that seems forced on me.
