Yes, that's the thing, it just takes time. All you can really do is be kind to yourself.
Learn about addiction but also about yourself and what makes you happy. Keeping busy, seeing new things, things that keep your mind busy and sometimes not so busy. It's hard no doubt.
The more you do that's new, the more you will find your mind thinking about that instead of anything else. As you've noticed, it begins to not be there, the thoughts, every minute, day by day it gets slowly better.
Hang in there.
