Breaking ribs through too much strong coughing ! That sounds very painful and unpleasent. I heard that broken ribs are close to impossible to treat.
The question of respiratory depressants is an interesting one, I can follow the idea in my mind that a small dose mght be good as it stops the coughing. But I worry that the dose might be too large and stop all breathing.
I once heard the tale of a man who wanted a new chauffeur. He took the three applicants to a nasty looking winding road which had a big horrible drop off the side down into the sea. He then asked the men "how close could you drive my car to edge without dropping it off the side into the sea".
Man one says "One foot"
Man two says "One inch"
Man three says "I would rather not go near the edge"
Man three was judged to be the best man for the job, he choose to not take a risk to show off. He was more careful. He would view is safety as more important than the thrill of driving close to the edge. I think that I am man three, I would rather not take a big risk which offers no or little reward.
While I am a chemist I am quite wary about taking drugs, I try to limit the number of new and exotic substances which I start adding to my body. But I am a great fan of a few drugs, when I get a bad cold I always try to get some lemsip pills.
