How to stop coughing every second?

I'm worried about today too!
I have an alevel S1 exam and I'm coughing like mad at the moment,
Try breathing normally, I find this helps a little

Drink plenty of water, and if u hav phleghm, try n get it out as much as u can b4 the exam- Neva swallow that **** man- it's infection. Finally- remember in 5 very, very short years ur Gona b 21 like me- working- and u won't even remember this silly cough or exam ok? So th only way ur Gona get thru this exam and do the best for you-I'd by coughing freely. Loudly if u will. The only thing that wil **** ur exam up the *** is ut self consciousness. Don't woz bout ne1 else-u won't remember them either so jus get ur head down n focus xx goodluck

Simple thing is that take a cordal flu with cough capsules. But if it is s allergy problem then take claraton tablet. I think you got alergy problem

try to drink some warm milk with honey before breakfast
