I'm glad your DH is trying low-carb. My ex-husband had the surgery, and ended up losing about 30 pounds. He went from 170 to about 140. (He's 5' 10'' and looked really bad until he gained about 10 back.)

He was constantly vomiting and we couldn't take our daughter out to eat without him running out halfway through the meal to the toilet (severe diarrhea) or home. I think his symptoms were similar to the stomach stapling surgery, since they took out part of his stomach and re-routed something.

I used to have such severe stomach pain that I'd take any pain pill I could get my hands on illegally, but since starting Atkins I have had zero incidents.
