As a wrestler, I think I can offer you some advice. Drink lots of water!! So much to the point where you think its ridiculous and too much. That will fill you up. Have 5 small meals a day. Wear those plastic or vinyl sweat suits when you work out. And workout at least 2-3 times a day. But after your workouts, as long as you have a few weeks, you can still have a good meal and not feel weak. Hope this helps. My last year of competing in wrestling, my final tournament I was 159 coming in to training the Tuesday before our Friday weigh in. 11 pounds in 3 days. Pretty dangerous, and I'm a pretty lean guy to begin with. Talk about dehydration
