Is drinking water a new thing for you right now? I used to NEVER drink water, just diet Coke all day long, until I decided to be a Big Girl and control my IBS with my diet. Now water is the only thing I can drink! I was pretty bloated at first. I was so dehydrated that my guess is that my body was holding on to the water because it didn't know what to do with it! lol. It went away after a week or so. I still get more bloated than normal around TTOM. But what else can I do?? If you've been drinking water for a while, though, and still have problems with pain/gas/bloating, then I don't know why that is. Sorry if I'm not helping.Jane
