I have been having trouble with fatigue for a few years now. I have had every blood test known to man plus tried numerous alternative resources. I basically live on caffeine. My wife had been telling me for quite a while that I have been snoring extremely bad. She said I would snore and quit breathing for several seconds and then gasp for air and start the whole process over again. Anyway I talked to my doctor and he lined up a sleep test at a sleep lab for me. They hooked me up with a shit load of wires and had a camera over the bed and I went to sleep. The next morning the nurse came in and said that I had severe sleep apnea. She said I would quit breathing 45-60 times an hour. I had no idea that I was doing that other than what my wife had been telling me. I don't think I had these problems until I started the hrt a couple of years ago. I thought at first it was the gh I was on for about a year. But I haven't been on it for at least a year now. So now I am going to have to sleep with a cpap machine and hopefully I will get some energy back. I don't think it will do much for my sex life but I am more of a morning person anyway. I guess the moral to my story is if your dealing with severe fatigue and can't pinpoint it you might look into sleep disorders. I have been living with this for a long time and wish I would have done something sooner. I am sure this has been discussed before but wanted to post my experience.
