I was thinking of doing the Phen as well, but the truth is if your band is adjusted properly(when you're actually losing weight) there is no need for it. I lost 40 lbs in about 5 month with 3 consecutive visits to my surgeon and keeping a close eye to the volume of food I was eating. The moment I notice I was able to eat more, I would call and schedule an adjustment. So far, so good. I was stuck for very long time and now back to losing, I'm so happy
