Medicine Log
With reference to a previous post I have made on this thread: KEEP A MEDICE LOG. Yes, it is a hassle, but like keeping your log book up to date and reading check lists it will help to keep you out of trouble.
I was first introduced to this practice by my first commuter job back in 1986. In fact it was in their Op's manual including what medicine one could and could not take.
Just do it.
