Poll on pain tolerance....
I had my gallbladder removed at the same time I had wls (both lap surgery). I quit taking pain meds the day after surgery and didn't take any after I got home. I was back at work 6 days after the dual surgery feeling fine.
It sounds like with your pain tolerance the gallbladder won't be a problem for you. I can't answer the one on tying the tubes.
Best of luck!
