thanks Jeff. Would you mind keeping me up to date on what you discover with your research into chronic fatigue? I have tried all sorts of things to try and over come it - including walking for miles and miles - made me lose weight and that was about it. Have tried trying to extend times between sleeps and all that does is make me play catch up for a week. Any disruption also prevents me sleeping at night and then I can end up staying awake for days on end. It does all seem to be a very very fine balance. My psychologist actually had me admit the other day (I am always in denial of all this even after 6 years!) that it takes me all my energy to simply exist at times! Oops sorry if I sound like a misery think I am having one of those days! Groan!!!
