Darth, I maintained my weight for years in a similar way. I wasn't starving myself, but I did eat mostly junk food, but in really small quantities. I know that it's not healthy, but it's so hard to choose a salad over pizza!
Good luck, Hydro. I need to lose some weight now myself, because I've gained 26 lbs on zyprexa. I've been trying something called the "5-2" diet; 5 days a week, you can eat however much you want, but 2 days a week you restrict yourself to 500 calories. I don't have a scale so I don't know how effective it is, but after a week and a half on it, the gap between my thighs did look a bit wider.
For me, I think the 5-2 diet is relatively easy to follow, mostly because most of the time, you don't have to deprive yourself. So maybe you could try it? Just please, don't attempt it if you have a history of eating disorders; I read that this diet is dangerous for people who struggle with EDs because they start restricting too severely on too many days.
