Does your body stop accepting lactose?
I've been at the hospital all day and I asked if they had any vegan-friendly items to eat.. and the nurse said "Oh, we have a veggie burger I think that's vegan" -- so I ordered that. Haven't ate in a few days.. so I ordered 2 of them, apple sauce, and side of rice.
First sandwich was ok.. and halfway through the 2nd one.. I got nauseated, stomach pain... and bloating (this was a course of 45 mins) , it was only slight-- so I shrugged it off and kept eating it...
About 2 hours in.. I had intense cramping. horrid gas. and had to use the bathroom (sorry for TMI,.. but it was quite a lot of diarrhea--like it's seriously all water and still going on).
I'm thinking the buns had some sort of dairy and or the veggie burger. I tasted a slight taste of 'cheese' like flavor (maybe?) I've been vegan for a little while now. (and been pretty strict with it). The only other time I mistakenly ate dairy (was around 2 weeks of when I went vegan) got a similar (less dramatic) reaction.
However, before not going vegan.. I never had this issue before (I don't mind it- as it helps me be more aware of what I'm eating). Could not having dairy cause an intolerance to lactose?
