Gotta eat huge to get huge, share your appetite-expanding tips!
I'll start off, I drink tons of water (around 1L after a meal and then 1L in between meals) and that expands my stomach so after I'm done taking a piss I'm ready for more food. The weakness of this is that one of my biggest meals is right when I wake up, so this doesn't work unless I wake up in the middle of the night to load up on water.
