As @Dazercat mentioned, getting involved in this community can be a great way to connect with people.
I would suggest thinking of fun things to do with your hands, to start. I know puzzles became very popular, but you could really do anything from playing with Legos to video games to online activities. You might be able to find groups online who play Jackbox games, which can be very fun.
But, things that you do by yourself, you can accompany that with tv, audio books, etc. This way your hands are busy and so is your mind. If you can find something to really get into and focus your attention on, that will help.
If you’re used to going out a lot, this may seem really mundain, but it’s something. If you’re inside a lot, I would recommend body exercises every day. This will help release good endorphins in the mind.
Eventually the urge to use will pass. In the beginning, you’re just looking for it to pass for that moment, then for an hour, then the day, and eventually you realize you haven’t even thought about it in a while. It’s all about training the brain and body to expect something else.
Best of luck to you.
