Sounds like you are pretty good at coming up with reasons why you can't quit Tetrax. And believe me, I did the same thing for a long time.
The thing is that your addiction lives inside you - so even if you could magically move to a new apartment and get a new job this very instant, your addiction would still be there.
So yes - certainly changing your surrounding could help....but the bottom line is that only you can make the absolute commitment to not drinking. And you can do that right now, right where you are if you choose.
