I wouldn't feel comfortable offering supplement advice unless you had a recent check up with blood work. Chronic fatigue can be caused by many things, and if ephedra isn't waking you up, then something could be wrong. Not to worry you brother, but if you haven't had one in a while, I think it's time to visit the doctor for a full check up. I'm sure there's nothing wrong but it never hurts, and getting blood work done is never a bad thing!

But above all, get a check up and talk to a doctor. Good luck!
