I've been taking adderall for narcolepsy and use a BiPAP machine for obstructive sleep apnea. A sleep study is helpful if you have a undiagnosed sleep disorder. Have you been allergy tested. Don't give up.

I found out my vitamin d was low. I started taking that and it helped. I stoped recently taking because if you take too much of it it can also make you feel the same way. I was also recently diagnosed with sleep apnea severe. Try to get those tests that may help.

Thanks for the helpful ideas, and I wish I could say that I could try those things, but I already have. The sleep study, the allergy tests, and I take extra Vit D as well after discovering I did have an efficiency there. I have tried everything for fatigue as far as medication is concerned. On my 6th (I think) try, I was helped a great deal by Adderall. That's just another concern for me though, because I've now been taking it quite some time and have reached the limit on dosage. I still think it's helping, but I also can't function without it. It really seems like a lose/lose situation at times, but it's really good to be able to talk with others who have the same or similar experiences or troubles. My goal has always been to fight against these illnesses, so losing isn't something I want to consider. I guess that's why we really are warriors!

Since taking adderall for 19 yrs, I believe my tachycardia was caused by it. I take Altenenol for it, and though it sucks to be on meds, I get to be awake without dozing off w/o it.

Have you tried pacing? It has significantly helped me get a better handle on my capabilities and energy.
