It's the only thing my wife takes when she is sick. I've been carded quite often 

I've never tried it. I spent a few years as a grocery clerk before going to college and a dude with dirty 1-inch long nails would buy three packs every couple of weeks. The manager would scan his ID (which might've been fake) into the database. Pretty sure he was cooking.
