Churning tummy >.<

Had steamboat last nite at bugis area.
Ate mostly vege and some seafood...
And this morning, woke up with a tight tension in my tummy. After a while, i thought it felt ok. So came to office... it started churning again... *cryz* Couldn't really do any work. The pain can be quite bad at times. Thought food poisoning... But once i step into the office toilet, the pain goes away... Walk back to my table, sit a while, the pain is back again. OMG... why like this...
haihhz.. maybe i shouldn't have been greedy and ate steamboat >.<
I think overate a bit ....but really we took vege, mushroom, little bit of fish and chicken, prawns and more vege. When i look at others eat... shesshh... i really wonder how the shop earns money.
Dun feel like eating lunch le... the pain, dun know is cramp or food poisoning or hungry. haihhz...
Cannot go home coz got so many things to do... haihhz... why like thissss
