Call me crazy, but i've started using bee-caps and my energy level is normal again. I found myself overtired for a few months and I had tried relacore, which worked for about a week but was expensive, then saw these caps while on vacation. I take one at breakfast and one at lunch and wa-la...no more sleepies. They're an all natural product put out by Nature Cure. Might want to give them a try. Here's a link:
