This post scares me since i am pre-op. I have been doing a ton of research and it appears common to regret the procedure. The posts are all over youtube. The feeling will pass and you will only regret not doing it sooner. I hope you feel better. Sending positive energy your way.
I thought of the same thing about getting my BMI up but decided it would be too uncomfortable. For my local BCBS doesn't approve the sleeve unless your BMI is 50. I am self paying because I am afraid to go to Mexico.
I wish I lived near you. I would pick you up and drop you off at home. It doesn't sound right to have to go through the surgery and not have his support. I think you should tell him to pick you up. You need to be accompanied for safety purposes. Maybe you could join a local support group. I am sure someone would be willing to take you home.
