weightloss pill?

I've tried so so so hard to loose weight. I've drank NOTHING but water and skim milk for the past 6 months, I've done a few work out sessions around my house (push ups, squat challenge, lifting weights) and I've been dieting. But I can not,for the life of me loose a noticeable amount of weight. What were your side effects while on the pill? I might go and try it out...
