I've been on the stronger drugs and haven't taken entocort, however, I wouldn't expect to see miracles in the energy department. I have a window of mental & physical "alertness" of about 4 hours before I'm ready for a nap. And yes, my B12 levels are fine, I take a good multivitamin every day and my CD is for the most part under "reasonable" control right now. I have to take a mid-afternoon nap EVERY day or I can not make it through the day. Exercise helps increase your energy and helps you sleep better too!
