You can do this. One question though - what area Kaiser are you a member of? California, Ohio, Mid-Atlantic? I ask because I am in the Mid-Atlantic and there is definitely a weight list for the surgery. So, once I got my approval from the board, there was about a 6 month wait before being scheduled for surgery. I just realized I spelled it the first time "weight", which I guess is also true.
I am a Kaiser patient...I had my surgery October 2012 and at almost 6 mos out, am down 75lbs. It really does work - BUT - it is also a lot of work. I work out EVERY day, which I never did before...And, I still track everything I eat. Good luck!
