Adderal and Ritalin are sometimes used in low doses in FM/CFS patients to increase energy and help dispelling the 'fibro-fog' that's present. Klonopin is another drug - used in low doses - which can help with fatigue which is somewhat ironic because its also a sleep aid; the key appears to be taking it in low doses during the day. 

Some people do well with D-Ribose - a mitochondrial supplement. You also should look at activity management; pacing - ie doing enough activity to keep you as fit as possible while allowing you enough down-time during the day to recover and heal - can be very helpful. 

If you're having trouble with sleep then sleep drugs can be really helpful for your energy the next day...

Of course speak to your doctor before taking any course of action. 

Good luck!
