Anyone know a Really good way to loose weight?

I've been exercising and watching what I eat. I only want to loose 20-25 LBS. I don't know any other way to loose it!! I have even cut back on my Vodka Oj's ha ha!! Is there a diet that someone has done that works? Or is there a diet pill that someone uses and has had success with? I'm desperate! I just got dumped and think that this might be a good booster for my confidence!!
