I'm 21. About 5'6" and I'm about 125 lbs. I've never had any issues with my weight or self image, etc. but I rarely feel hungry at all. Living with my girlfriend helps, but sometimes I just can't remember to feed myself. I don't have any trouble eating when I do remember, but I've gone 2-3 days before realizing I havn't eaten anything. Is this some sort of disorder? Is there anything I can do that might help with my appetite?
