Fatigue is a big problem for me also though recently my energy has gone up alot because of a supplement called D-Ribose. not sure if im allowed to post the brand name i use here but you can email me privately and i will tell you.
i would say my energy level went up from about 40% to 70% after a few weeks of using it at 5mg 3 x day. im always trying different things for energy and so far none of them really make much of a difference but this one is supposed to help with muscle energy atp and ive been able to exercise so much more since ive been on it. i know everyone is different but maybe it is something worth trying for u? i tryed Provogil also but found it increased my pain levels and made me feel edgy (tho that could have been the pain
hope you find a solution soon, dont give up, something will work for you it just takes a while to find the right combination of things.
