I "invented" a new drink this morning, really helped me out.
"Pipe Cleaner"
Ingredients:
3/4 cup of boiling hot coffee
2 shots of Drambuie
1 shot of Whisky (Irish or Scotch)
1 tsp of raw sugar (brown sugar works too)
Juice from 1/4th of a lemon or lime
Make the coffee, pour in a cup, then top with other ingredients, stir well.
Hold nose, chug. You'll have all your sinuses cleared pretty quick.
