Obviously see your doctor but some things that helped me:

• sleep upright or at least elevate your head. I had an awful cough while I was lying in bed recovery and I just saw up and it went away.
• there is a pill - forgot the name of it - but it basically short-circuits your throat where you don't have these chain coughs. It's a clear yellow gel pill and used in pneumonia-related situations so I'd ask the doctor if it's a recurring problem.
• not terribly obvious but take allergy medication. Coughing often results from mucus draining down into your throat. Allergy meds often dry up the mucus in your nose. No mucus draining, no coughing.
• try those throat sprays but this depends. You need to literally spray the throat but if everything is swollen then you'll just numb your tongue instead.
• there are cough drops that include a numbing agent but, again, will mostly numb your tongue. I've had better luck with Theraflu.
• wash your sheets and open your windows. You coughing might be worse if you're re-breathing some nasty stuff. If you haven't dusted in a while, put a mask on, dust, then keep the windows open for at least a few hours and let it vent out. If you're sick, you should be washing your sheets at least once a week, more if you're also sweating. This includes pillow cases and change your pillow if it's old.
• this might also be harder to do depending on how sick you are but go outside for a long walk and go to a park or some place with fresh air (i.e. not downtown or a subway). Take long deep breaths and yeah, you'll cough but keep going.
• you can also gargle with salt water if you also have tonsil-related issues
• take a hot shower and take in deep breaths, it'll break up some of the crap you have there
• if you cough and it's dry then that's one thing but if it's wet (i.e. you have wet crap in your throat) then don't swallow it back but spit it out. If it's yellow or green then your body is fighting an infection and just spit that shit out.

Lastly, as in anything, take a break, try to reduce stress, take some days off, stop watching anything stressful (ex: scary movies or tough video games), maybe even get off of social media.
