3 weeks is pretty long you’re past the worst of it

First week is the hardest and then it’s smooth sailing

You’re probably just bored keep your mind active on something

Find a hobby

weed withdrawals last no more than a week

your tolerance is probably reset by now so you could smoke again

your irritability is probably coming from something else maybe just boredom
