Dont Fret!!!!!
This is the way the procedure goes. The first 4-6 weeks is for you stomach to heal and for your stomach to have the time to let the swelling go down. Your stomach has been through alot and is swollen and has stitches in it and is sore. There is no room for a fill right now.
I too felt like I was losing time. But hang in there and let your stomach get used to having a band around it. Most docs do this I'm assuming because of the swelling. If you had anything in your band right away, I guess it would be hard to tell if it was a proper fill until you are healed.
Take your time, heal yourself, and just think to yourself, it took you how many years to put the weight on, a few more weeks will be ok. Stay focused and you'll be ok!
