You're not alone. My doctor talked to me about it in 2011 and I wasn't ready. After dieting on my own for a year and losing only 25 lbs. I was ready. After being banded a year ago, I've lost 115 lbs. so yes...this was the right thing for me to do.
I was at the same place over 2 years ago. I could not afford another failed attempt, it had to come off, my life depended on it. I made the call...I was right.
