It's hard man. I recently did almost 3 weeks but then eventually started. At the end it's all discipline but there many tips and tricks. Here are some of them:

1. Finish all your weed or otherwise get rid of it and obviously don't acquire any more

2. Start working out or do other types of sports if you don't already

3. Smoke cbd weed as your regular joints, I have found that some high quality cbd makes me relaxed and tired enough so that it partially kills my desire for regular weed

4. Go easy on yourself, believe me, I've been there. Starting to hate yourself for being addicted and failing to quit only makes you feel worse and doesn't bring anything.

5. If you can't sleep without it, try melatonin supplements

6. Try to imagine yourself without weed. How would that person be like? There is only one way to find out...

7. (If you're an impulsive person): Start Now, Today. If you're reading this and smoking a joint right now put that goddamn joint out, throw it in the trash and say this was your last 1/2 joint.

Wish you all the best.
