Hello, I think I have IBS as I seem to have the same symptoms. Bloating, constipation and Diarrhea etc. I tried giving up certain foods as I thought I might be having a reaction to something I had eaten, then reintroducing it again to see if there was a reaction. I reintroduced dairy today after 4 weeks without and was OK all day, then I had a milky hot chocolate. I bloated up with gas and spent the requisit time in the throne room. I have been like this for a few months now.
