I am knew and had the sleeve on may 9th. My worst fear is that it won't work. I don't know why I feel that way but its reality. My first week I was down 2 lbs but was dealing with some retention issues. I dont kn ow what to expect the first few week with weight loss. I found this forum and hope it helps me accomplish my goal of becoming healthy. I seem to be able to eat more than I thought I would which concerned me.
