There was a study where they gave lone rats in small enclosed spaces with zero stimulation the opportunity to self-administer cocaine. They all quickly became addicted. Then they gave rats in a large high stimulation environment, with lots of other rats, the same opportunity and they didn't become addicted.

Ice works by the same addiction routes as cocaine, so the results transfer to your predicament. I suggest you get yourself a wide variety of stimulation, and before you go anywhere know where you're going after that. That way you have less idle time for addictive thoughts to wander in. So, say you decide you're going to visit a family member. Figure out what you're doing after that: going to grab a bite to eat, say, and before you go to eat figure out where you're going after that. And try to get about all over town, and do things you wouldn't normally and/or in places you don't often go.

It doesn't have to be amazing stuff, just lots of variation. Instead of grabbing food where you normally would, go five suburbs away and find a new place, for instance. Just getting a bite to eat could take up half a day if you want it to.

What you're trying to do is rewire your reward centres to everyday life again. Try not to go to any place you've used ice - it will be associated with the drug in your mind and trigger cravings. You'll probably be tired due to withdrawal, so be realistic about planning things so you don't set yourself up to fail. Make small goals you can easily accomplish so you are using your reward system often. As it strengthens make the goals harder.

If you're really addicted hard there's a plant called tabernanthe iboga that will cure addiction with one dose. The active chemical is called ibogaine. Check your local laws to see if you can get it. It's a powerful hallucinogen also, so do your research.
