Hello everyone I was a heavy smoker for 20+ years. I just smoked my last cigarette 0n 05/02/2016 at approx. Noon. Lol that was when I purchased my CoolFire 4 mod box and Aspire Cleto tank. So far so good. I'm on 3mg/ml going down to zero nicotine by this weekend I have a urine nicotine test for surgery on May 25, 2016. Having a pretty hard time. I've been 15 days no cigs! Trying really hard. My cravings, mood and over all attitude have been horrible. Any advise would be welcomed
