Yep. And on top of this the drunk me wouldn't think twice about getting a round in for £40. And he wouldn't even remember handing over the £80 for the gram of coke later. An 'average' Friday night could see my bank £200+ down. I feel sick to the stomach when I think of this, and the arguments it caused with my wife, and the clothes & holidays etc that could have been.
I'm using this sick feeling as a tool now whenever I think about picking up a drink!
