I have had the exact same symptoms for 12 years and was diagnosed with Multiple Schlerosis in 1997. If this is illness is diagnosed for you then you should get on an MS drug therapy right away. It really does help! I have been taking Betaseron for the MS as well as Provigil for fatigue. The only other things you can do is to stay out of the heat and don't overwork yourself. Take breaks every 20 minutes if you are standing for long periods of time or looking at a monitor too long. It is also attitude! Stay positive and keep an "I can do anything" attitude! Works for me. :)
