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.
