Over The Counter Appetite Suppressants

My body is not bangin right now. I am 19yrs old and I need to tone it up before I can never get it off. So I have decided to take diet pills to help out some what. But I don’t know which ones are the best. I am trying to drop 4 dress sizes. But my goal is to fit into a bikini by Christmas because I am going to the dells. I will be working out along with taking the pills so please give me some names of diet pills that make you drop weight quick.
