Fasting. I lost 80 pounds starving myself, but you can't do that forever, and I gained it back times 2 because I wrecked my metabolism and had no idea how to eat healthily.
Alli but I didn't really give it a fair chance. I would forget to take it half the time.
Fenphedrine (pill). Made me vomit. Tried it a few times and every time my heart raced, I couldn't sleep and I threw up. Did suppress my appetite, though

And in the category of did-but-didn't, there's Medifast. It actually works almost magically. If you follow the plan, you WILL lose 2-5 a week. However, like Sockerton said, it tastes like crap. I mean horrific. Half the food I could force down; the other half made me gag so bad I couldn't swallow it. I spent two months eating the same few "meals" over and over (hot chocolate, crunch bars, tomato soup, pretzels), and that is allowed since they're all nutritionally interchangeable, but I got so sick of it I can't stand to think about it anymore.
I couldn't ignore how well it worked, though, so now I'm following the Medifast plan without the Medifast food: 800-1000 calories, <100g carbs, >70g protein and 10-30g fat. It's working just like it did on Medifast, of course. It's a little tougher to follow because your food isn't all laid out and choices are involved, unlike Medifast, but it's worth it to avoid the sawdust-flavored goop they pass off as food. *shudder*





and I am hoping I can find something to help me. I cannot work out until they get my foot right but I do some crunches and lift a few weights but there is not a lot of Ooomph as I very much miss my walking and hiking which I have not been able to do for nearly a year. I have never tried any pills as I am a coward and just afraid they might do something bad
