Want a very effective all natural solution?
Take a shot glass fill it with orange juice, add three maybe four drops of concentrated oil of oregano (no more than that) and shoot it down the hatch. Literally 5-10 minutes later you'll be all cleared up.
It is amazing.
If you want even quicker results and can stand the burn, take a drop of oil of oregano and rub it on the roof of your mouth. I warn you it's not terribly pleasant but damn it will clear you up in a hurry!
