That don't really count brother.  I mean you just need to not stay drunk or start doing heavy drugs.  A little weed and alcohol in moderation isn't going to hurt you.  You don't want a habit though dude.  And you don't want to alienate yourself from your friends and family.  Which a habit will definitely do to you.
When I said it took me a couple years to get totally over it that was true, but the bad part, the part where I didn't give a fuck about anything anymore, was very short.  It's kinda like quitting smoking.  The first 5 days without a cigarette damn near drive you mad.  After that it's still tough sometimes, but you aren't just fucking miserable anymore.
Keep yourself busy.  Work a shit ton of overtime.  Study jazz. Find you some pussy, but don't get attached.
