Well I would say count me in as a surgery supporter,
I am scheduled for a Lap-Band in January,
I have been struggling for 20 years with excess weight and skeletal issues, so everyones mileage varies.
In an effort actually answer the question there are a bunch of ways to finance
weight loss surgery,
(I tried to post you a link but I havent posted enough to do that yet)
There are also a lot of options to take up if your insurance company does not cover it (i.e. appeals etc)
If you want to send me a private message I think I can give you some names and numbers to call.
