Hi E.,
My mom had gastric bypass five years ago...so have my two uncles and one cousin (I guess you'd say obesity runs in our family!). They've all had great success, but this was after trying truly every other option and the change in lifestyle afterward is not neccessarily easy. No carbonated beverages and very small meals that aren't too high in fat or sugar or you get very ill. Some people have a bigger struggle with this change and develop other unhealthy habits. So, it is a big decision.
I don't have a lot of recollection of the recovery time (I was a newlywed and have since had a baby, so my memory is shot!), but I think that should be easy to find out with a little research. I was living with my mom at the time and I do remember that she needed some help for a while, but mostly it was obvious stuff like lifting things for her and preparing broths and jello for her (this was all she could eat for a little while). There were also a couple times that I helped her change her bandages, but nothing too scary.
If you're in the Tri-valley area, I recommend checking into Valley Care's program: http://www.valleycare.com/programs/bariatrics.html
This is where my mom had her surgery and she received great care and a lot of support. My mom's surgeon was Mary E. Estakhri, M.D. and she's lovely and highly respected. You can find some testimonials, etc. on the site as well.
Bariatric surgery is not the only way, but it really helped people in my family. I would say none of them regret it and they're all looking fabulous.
I hope this is helpful to you...best of luck to you.
