A friend of mine has this. He seems to get it every couple of years or so apparently, and it takes a much longer time (a couple months or so) for it to go away. First time I saw it I thought he had a stroke - was relieved to hear differently.
His best friend makes vicious fun of him (it's how those two are all the time) calling him Droopy, or Drooler, etc. Considering he's like 6'7" and probably weighs in around 300lbs it's a good thing he has a similar sense of humor lol.
Glad to hear it's already going away for you HHF
