I don't know where I get it from either. I just get by one day at a time and not try to figure out what I'm doing in more than one day. It is easier that way. I struggle too to be sure... I had a small pizza the other night. At least I didn't have a large or xtra large. lol. The med I take has helped a lot-Topomax. it has made my appetite back to near normal, really!! yes!!
