Crash Dieting

I'm not sure if I've talked about this one friend I have yet...she's getting married in a few months and can't fit into her dress all of a sudden. She's normally really good at maintaining her weight but it seems stress is getting the best of her. Now she's on the hunt for the best weight loss pills since fasting isn't something she wants to do and eating right is already being done. Frankly, I think fasting is one of the worst ways to lose weight anyway. It's a good thing that she isn't pregnant and can take some weight off however she needs too because she paid a ton for that dress. Why is it that they always buy the dress WAY too early?!
