Dude, I'm the exact same way. Breakfast, lunch and AM early PM snacks...I have to almost litterally choke it down. Early PM and on, can eat no problem. I'll eat a lot late, then wake up with an empty stomach, almost like I want to puke from being hungry, but its such a fight getting food down. Im genetically thin and lean, so its always been a struggle.
Look for my post on Pancreatin. This and pancreatin together have changed my appetite completely.
