Hard Cough

Right it’s 3 in the morning and I’ve been coughing non stop for an hour now. I have no cough medicine in the house and none of the shops are open for me to get some so does anyone know if I can do anything to make this go away quickly and make me go to sleep?

Please help me, thanks guys.

Hot tea, honey or just heat water and inhale the vapor it will clear your system for a bit and it feels great.
