I have been on a gluten free diet for 2 months now, and had noticed a slight improvement.
I got a stomach bug last week and the doctor gave me a shot of Stemetil to stop me throwing up.
I now don't have my IBS symptoms. Could it be the stemetil? It seems to go through your system very quickly, so I would be surprised if it is, but I can't think of anything else.
Even if it is, I'm blown because the tablets have wheat starch in them!
