I found out during my first visit 11/27/12 that I was already filled 5.4cc the day of my surgery which was 10/24/12. I just got my 2nd fill yesterday 1-9-12 that I really didnt need since they filled so much so soon. I'm at 6.6cc & am down 23lbs. I didnt have to do a pre surgery diet or anything because I am a a self pay. Its working out pretty good, considering I dont excersize, but I just joined the gym & will start MOnday
