I used to have a ton of gas but have it totally under contol with diet and probiotics. When I did have gas, there wasn't much of an odor. For the past two days I have been passing the most foul smelling gas. It is horrible and extremely embarrasing. The only thing I can think of that might have brought this on is that I ate sushi the day before it started. I sure hope this doesn't become something chronic. Anyone ever get this for a few days then it goes away? Any ideas? Thanks.
