Stomach upset again

To-date, I have been quite a frequent visitor to the toilet (home, hotel or office). Now considering if I should just move in there.

Sat - 2 times
Sun - 4 times
Mon - 5 times
Tue - 3 times so far

And yes, my stomach feels weird, asshole burning and rough now....

p/s: I need a more luxurious toilet, like the one in Shangri-la hotel is not bad. I would have preferred the old Paragon toilet (if anyone remembered) where each cubicle is as huge as 2 bathrooms. Still got sofa around entrance for people to rest after shopping (my long record there is about 1 hr).
