The break up is still raw Teddy (I also split with my g.f last week) and alcohol does seem like the answer.
But it's merely a direct route to pain, and you know that. If you are like me, you'd make a drunken call/text to your ex and possibly make things worse by having an irrational conversation which does more harm than good.
I am also teetering on the brink of drinking due to a broken heart, please try and distract yourself in any way possible. I know it's not the most sophisticated advice, but it's from someone going through exactly the same thing *and only 6 days sober.*
