I am 5 months post op as well and I have not for one second regretted my decision to have RNY. I am down 82 lbs and 5 sizes. The most important thing is I have my health back. Diabetes gone, high cholesterol gone, sleep apnea gone, and most importantly i had stage 3 kidney disease and my kidneys are functioning normal!
There is a lot of change that comes with the decision but I don't even mind the change. It is good healthy change! I was very ready and did not have a single doubt going in. I also had a very supportive husband who had my back.
Don't second guess yourself but do make sure you are truly ready. If you are having doubts you should talk to your phsycologist. They will help you work through them.
Good luck and keep us posted.
