Let me give you a recipe for a happy Dug:
1 liter ginger ale
1 half pint of cheap whiskey (I prefer Old Grandad for these but I'm to lazy to walk beyond the closest liquor store...)
1 violent video game or bad movie.
Drink about one pint of ginger ale, add whiskey, and enjoy fairly strong drink that's good for the digestion. Add violent video games, snacks and bad movie as needed for a night of solitary fun. If you favor a slightly less whiskey flavored drink leave a couple of big swigs in the half pint for later enjoyment when you need to fortify your courage.
Yeah, possibly pretty sad I know but I had fun killing nazis late into the night.
