Any pointers for post-prednisone fatigue?

I've been on 2.5 mg of prednisone for 5 days and today is my first day without any. The last week I've been unreasonably tired. I've been sleeping for a minimum of 12 hours a day. I got off work at noon on Friday and I'd wager that between then and now I've only been awake maybe 20 hours. The only reason I'm up right now is because I have to go into work. Other than dropping a million dollars on Red Bull and 5 Hour Energy, is there anything out there that will curb this insane fatigue? And how long does it usually last?

There is some good news - I don't look like the Michelin Man anymore and I've already dropped 10 lbs. My appetite seems to be back to normal and there hasn't been any change to my bathroom experience during the taper.

The recovery rate has been different each time I've been on prednisone. I think it depended on how ill I was. The average recovery time for the fatigue was 2 weeks. Non-impact exercise does help. My joints become very swollen from the pred. and can take up to six months to completely disappear. Blood sugar levels go back to normal within 2 weeks. Vision takes about 3 weeks to go back to normal. Everyone is different in their recovey rate.The younger you are the faster you will bounce back. Good luck!
