So for awhile now I have cut out sodas. Specifically Pepsi and Coke. However the past few days I've decided to have a couple and noticed that just tonight (about 6 hours since the drink) I'm having terrible pains, bloating and a little nausea. My BMs have been burning too although consistency is pretty normal. A lot of gas though. It seems that this is a common occurrence if I have soda. Does anyone else have IBS linked to soda and/or is this fairly common? It feels like someone is stabbing me directly in the middle of my upper abdomen and it's very crampy feeling.
