Weight loss help, i need some good advice on diet pills?

[Valentina V]

I pretty much dont know what to do anymore. Im 23 n I work in the morning and have school at night 3x a week and sat morning. Im always tired and i need to exercise!! Im thinking of quitting work so i can take care of my weight.
Im going to Europe in June and i need to loose about 35 lbs. Im 5'9, i have a large frame, i will never be a size 0, i think the smallest i can be is an 8 or a 6, I'm a 13-14 now.

What can i take? Do any diet pills work? Also i am dieting, i do great throught the day but at night i need chocolate, or something sweet so i give in, i hate myself afterwards..ugh!

Im a mess, ive been overweight for the past 2 years, on n off, joined a gym, stopped going and now its expired. I can't afford membership but i do have an elliptical at home, plus my fiance has a weight bench, so i guess i can do something there.
How do u get the motivation back? If i take diet pills will they give me enough energy to do it?N if you know of any good kinds that work fast...
Should i get a detox, like flush the fat? And what do u do to prevent sugar cravings
