what's wrong wif my stomach??

wah...how come these few days kept on doing big business???
so tired and like....hate my stomach!!!perhaps this topic very disgusting, but this's my feeling about my stomach.
As I known, I'm a person that easily to vomit out everything once I ate too much since small.
But after seek a tabib, my stomach is getting better but then if after ate curry or drink ice water, sure stomach din felt well again.
Once again, hav to seek another tabib to treat my stomach. But luckily god blessed me, my stomach is getting well than before.
but I dunno how come these few days  not feeling well, always went toilet.
Am I too stressful? or too tired? ate too much??? or got something wrong wif my stomach...
WIshed everything will be fine after 2day!!!cos i stil hav final exam to go after this week!!!!!!!!!!!!!
God bless me...THANKS!!!
