I was mid-way through my 6 months course and found at that my insurance didn't cover it due to an employer clause, not because I wasn't qualified.
I resigned myself to the fact that I wasn't meant to have the surgery. Within a few days I did some research and found a company CreditCare that provides a credit card limit for medical procedures. I struggled with whether a $15,000 debt was worth it. My answer, of course, my life is worth that and much more! As one other bandie said, it is an investment, one that will give you a better quality of life and a longer one too!
I had my surgery two weeks ago, I'm down 12 pounds so far and thankful every day that I did it! I hope this helps!
