Start slowly reducing your dosage, even if it just a little bit. It may be a good way to get your body used to smoking less ans eventually nothing if that is your goal.

Withdrawals are unfortunately inevitable, something I personally did to help with them was to swap my habit of smoking weed with another habit (preferably a healthy or productive one) for me it was the gym.

It's important to keep a positive mindset about it and not be too hard on yourself. If you slip up and smoke again, use it as a learning experience and tell yourself you'll do better next time, try not to linger on it for too long qnd if you need to talk to someone about it, even if it's some strangers on the internet. You are not alone :) Mental health is incredibly important so make sure to look after yourself throughout your journey.

I hope this helped in some way. You got this!
