I had a coworker who came in with a headache. Our receiving dock manager overheard and gave her what my coworker thought was a couple aspirin. Turns out the manager gave her a pair of Vicodin tabs without telling her. Needless to say, she wasn't doing anything for most of her shift and the receiving manager was kindly told to GTFO.

I take Xanax but only for very specific things with a limit time period. Notably for visits to the dentist. Turns out dentists don't like it when you cry uncontrollably and getting therapy takes too long when you need a root canal. So two Xanax for the visit and for no other time for me.
