my tummy

For as long as I can remember, I have a very strong stomach. My stomach can withstand all types of food. Oily, spicy, sour, salty, sweet.... you can call me MPPP!

But my stomach's ABILITY has declined a lot lately. I can no longer eat food that are too oily, too spicy. I'll have a bad tummy ache the next day.

Example, get me a bowl of yummy tomyam and see me going in the toilet a few hours later! Even KFC sometimes makes me visit the toilet! T_T

But still this itchy mouth of mine cant resist the temptation of food. I guess that explains the regular diarrhea... or even food poisoning!!

HELP!!!!!!

Any good remedies to cure me?
