Dextromethorphan: my new word for the day

I finally looked up cough suppressants online, after days of little or no sleep with an annoying dry hacking cough, and have now gained by my illness. I now know that it is the dextromethorphan HBr in my pills that is supposed to take care of cough suppression. I had been wondering all week what purpose there was in ingesting bromide in any formula, for any illness, but now I know it is not the bromide, but the other part of the chemical name that is important. Maybe the bromine stays stuck to the molecule and just the H goes off on its own, and leaves dextromethorphan-Br to hang out in solution and bind to stuff with other loose H's. obviously I did not get very far in organic chemistry, cause this is probably all semi-educated rubbish, but it makes me feel better about my pills, now that I know what I am looking for in them. Now so long as they work, maybe I can sleep tonight and wake up cured in the morning in time to go back into Boulder for work.
