None. I had quit for a week or month a few times over the years.
I had scaled back for a while, so it wasn't cold turkey.
I never felt any physical symptoms every time I quit. It was more mental and yearning.
It had become a daily routine, and routines are usually tough to break free from. I don't really miss it, but when I spell someone smoking some primo, I do feel like a wanna toke. When I go back to Maine every summer, I usually partake a night here or there.
Once or twice a year is it, now.
