feed the machine.
if your body wants food...FEED it and grow
also, when i was trying to gain an insane amout of weight...i would stuff myself till i wanted to puke. Then i would leave the kitchen imediately and not dwell on the fact that i ate so much and feel like i'm going to puke. If you dwell on it...you probably will puke...just get in, eat, and do something else.
