So i just recently came to college and I must go like 3 times a day where as back home I would be like once. Is it the food not settling or what? I've started working out the past week and half too but i don't know if that is relevant.
Rad is probably right, though another possible explanation is that the kitchen workers' hygiene leaves something to be desired, and your system is having to deal with a few more bacteria than it used to. If that's the case you should get used to it soon. (At a place I used to work at, a former cook was notorious - everyone used to get diarrhoea for the first couple of weeks.)
