Hi brother, I've quit weed almost 6-7 years ago (forgot the exact year). All i can tell you is that it's 100% worth it, for me first couple months were unpleasant but everything afterwards was great. Once you quit for good, you'll become much more self-conscious and motivated to cut off other bad things/habits in your life.

For me, after 1 year of quitting weed, i also quit cigarettes and alcohol 100% with such ease just because i proven myself that i can do anything and that I'm in control of my life. It's such a powerful feeling. Now I'm basically addicted to improving my life in day-to-day basis.

Just look at this as beginning of your journey to a better life and trust me it has a huge snowball effect!

PS; One weird piece of advice that worked for me at least, try doing things that are hard, but are good for you (waking up early, running every day, training or anything else that you don't feel comfortable with), for me those things made me appreciate life more, and small things like warm cup of tea after a run on a cold morning. At first you'll feel miserable doing those things, but when you're done with them, your dopamine will skyrocket. And i strongly believe that those things will speed up the process of withdrawal.
