I'm a lap-band failure...my lap-band has never done anything for or with me...I am now back up to my pre-surgery weight I moved to another state since my surgery so next Friday I am going to a new surgeon....maybe I'll speak with him on the lap-band to sleeve conversion. I'm so sorry to hear of others having problems; I've not experienced any problems other than slow weight loss, constant hunger when trying to eat small portions and now right back to where I started. I suspect my previous surgeon never really filled my band as much as he could have.
