So the past few weeks I've been having some weird stomach problems. During the day I'll feel hungry like normal, but during or after I eat I start to get INTENSE hunger pangs. This makes no sense to me because I don't feel that way before I eat.. but after or while I'm eating, I will all of a sudden feel STARVING like I haven't eaten all day. It's so weird, and nothing I can find online gives me any answers as to why this happens. Is this common or is my body just going crazy? :p
