I am so much older than you! I'm 46, and I have two little boys who are 5 and 8. You are so wise to do this at your age.
My recovery was really fine. The first few weeks were rough, and I got a bad case of the flu, even though I got the vaccine. But gradually I got stronger, and I had no problems relating to the sleeve surgery at all. Best of all, I've lost 90 pounds in seven months! No regrets at all.
I would be more than happy to answer any questions or offer any support. You will do great!
