Adderall and Provigil can be used for chronic fatigue but it is no cure. For me neither one was all that great. Only prescription meds I can think of. Over the counter, no, you can try vitamin suppliments, but the problem is, you need to get to the root of the cause of the fatigue, or your going to have to learn to just live with it.
I have had chronic fatigue for 1 1/2 and people would tell me that it was because i am a full time working mother of 2, blah, blah, blah. I started doing some digging and self diagnosing, come to find out i suffer from hypothyroidism and also have a mass in my thyroid. I'm having sx in 2 wks to remove thyroid. Problem fixed. I knew i wasn't crazy. Keep digging and get the thyroid checked. Good luck.
