I've battled the same thing before. Have you thought of doing a short round, and losing the 5 lbs, and then adding calories to 800-900 until the 23 days (as suggested by Dr. Simeons). Or another idea would be to try a low carb diet for a few weeks (think Atkins induction). I agree it's tricky to know what to do. Congrats on being where you are right now though!
