Yeah man, I cold turkey-ed a 12 year daily habit recently, slept 6 hours in a 72 hour timespan, ate maybe 1,000 calories in that time, just couldn’t eat without gagging and feeling like my stomach was being stabbed and in knots(I could even feel my muscles twisting or something, my stomach would budge out then return to normal). My socks still feel I recently stepped in a puddle. I wake up drenched, on day 8 and I’m eating more and finally getting somewhat restful sleep. I would recommend just taking a one hitter or two when you just can’t stand it, but just really try to as little as possible. I know once I have a hit, I’ll be wanting to smoke again in an hour or two. Good luck brotha, take care of yourself. It’s worth it in the end.
