I had my first fill on January 25, 2010 and I didn't notice any difference at all. I am hungry all the time. However, I go to the support meeting and they tell me that is normal. It's 2 or 3 fills before you really notice a difference for most people. My doctor will not let us go for a fill more than once a month. I get my second fill tomorrow and I hope it makes somewhat of a difference. Just to let you know, I didn't gain any weight. I kind of just held my own and I'm eating. I also bought the Weight Loss Surgery for Dummies and it's a really good book. It explains that you will be more hungry than normal but not to worry that will go away.
