i never feel hungry either, unless im starving.
but after a while i realize that i haven't ate in a long time, like if i see someone else eat, i think about when i last ate. then i eat.
if i don't feel like eating and i have trouble swallowing, i force it down, because if i don't force it down then, it will be even harder to eat later.
i dont know why this happens, i've been meaning to get my self checked out. but i guess since im still healthy its ok, cause i do still eat 2-3 times a day.
i hope this helps...
