The talk about drug interactions reminds me of a real BoZone stunt I pulled a number of years ago.
I had a very bad cold and before I went to sleep I set a bottle of Breacol on the nightstand so I could take a swig if I started coughing. Late that night, I needed to "hit the bottle", and not wanting to wake my wife, I left the light off and grabbed what I thought was the cough medicine - it wasn't.
It was nail polish remover.
The wife told me that the noise I made when I coughed that crap up was the most God-awful sound she ever heard in her life....
