Last Saturday, after I first ate, I was struck with a bad stomach pain that lasted the rest of the day, a little into Sunday, got worse on Monday and then vaguely on Tuesday and then I haven't had it since. I've also had nausea after meals and when I wake up, and I get full quickly. I sometimes get hungry but even a drink of water can make me feel full for hours. I'm thinking that maybe it's IBS, since I've had anxiety and depression for a while, but the symptoms came on rather suddenly... I had a brief period of vague abdominal pain a few weeks back, but it was more annoying than uncomfortable and nothing else was wrong. Does anybody else have IBS, and if so are your symptoms similar?
