how to cure cough?

Option A: Drinking heated coke (with lemon or ginger or something). I remember hearing this from some TV programmes (hey... sometimes there are useful info as well). I am abit more lazy, so went ahead and just drank from the can itself.

Option B: Drink lots of water. In the day most of the time I am outside, so I try to minimise water intake so don't need to go to the toilet too often. Hence at night I try to drink more. End up cannot get to sleep because keep getting up to visit the toilet. At least something good came out of it, I went to study since I could not sleep.

Option C: Eat/drink cough syrups/medicine etc or visit the doctor. Again being the lazy and stubborn Wrath who refused to see doctor unless I am dying, I decided to look for some medicine at home. Thought of taking stepsils but realised it is for sore throat. Anyway I still took it.

Option D: Heck care. According to my many years of experience playing volleyball, the body will knows how to cure itself. So its only a matter of time.

Either I get worse of get better right? Much easier than all the physics and math I am doing...
