Ok, but how do you drink coffee then?! Jk, gzz, sir!
After 10 years of 3-5 packs / weekly I was able to stop for 3 years, but not cannabis actually.
In my case what helped was meditation to fix ADHD and anxiety instead of smokes...
Went back 5 months ago lol, for the past 2 weeks I smoke 2 cigarettes/day at most or none. A not recommended habit for sure.
It would be a mess to get heavily into it again until feeling the urge to break it.
But yah know, wp, do your best!! Cheers
