We finally went to a doctor when I could muster enough strength for a quick shower and that painful walk to the escalator and down from the apartment to the car. We went to a clinic I've been to once before, I assumed it was due to gastritis (that's practically the only reason I ever go to clinics). First thing doc said to me when I came in was, "have you done anything about your back?" I was so shocked, I was like how did you know??? Apparently the reason I saw him last was because of my stupid back.
Turns out I didn't have food poisoning like what I assumed on my own. Instead, I had chemical poisoning (it happens when you eat preservatives or spices your tummy is not used to). Thank God for the drugs, helped me made it through my presentation in class later that night. And my lecturer was impressed... Though I did miss out a few things. :D
So the tummy's still not as good as it used to be. I've stuck myself to eating soft food (nothing fun) and the trips to the toilet ain't anything fun either. At least there's one lesson you can learn from here: be wary of the things you put in your mouth. (>_<)"
