I wonder if I took about 1/2 a teaspoon a week of Cheratussin cough syrup (contains codeine) for my intractable chest congestion, (from allergies) if it would be okay. I ve tried multiple things, mucinex, antihist., humidifiers, etc. and none of them begin to work as well as the cherrarussin. I know its addictive and bad to take long term. But I have no addictions, and I would not get addicted.
