Morning ozhondie.

I have a B16, but you see this isn't the issue. I've had really, REALLY bad diarrhoea for the last 3 weeks. Like to the point where I have gone to hospital 4 times and each time they have given me a drip. At what point do you guys think that McDonald's is the culprit? I only have it 4 times a day at minimum, I don't think it's excessive. Thoughts?
