I want to give up cigarettes, i don't know if saying I'll start some other date that NY is just the addict in me making excuses & procrastinating.
Find an outdoor job to volunteer at max, something like the Nat Trust fence & hedge mending or a community scheme. I know it sounds like a pain in the ass but it's a good way to stay focused, I bet you'd work with some sound people and grow to love it. In the spring loads of woodlands and stuff want volunteers and often provide transport. Its nice work where you can just get your head down and work on your own but have a chat if you want to, and a good stepping stone back to the disciplines of a job. And you never know what opportunities may come from it.
I know it may sound naff, but don't dismiss it out of hand. It'll help you in your other NY resolutions. The physical tiredness alone helps combat cravings when they crop up. You're vulnerable just knocking about aimlessly.
If you want to PM me your approx area I can help you look for stuff if its a help
