I've smoked for about 6 years now after quitting for about 15 years. Just ordered a voprizer for myself and as soon as it arrives, the cigarettes will be gone. I'm going to start with the oil that has nicotine in it and slowly mix less of it in with the non nicotine oil. As I just turned 40 I realized that time is getting shorter and every day I can extend my life by quitting, the better I am for it.
Stop now. Stop right now. You did it before. You can do it again. Do not prolong the agony. The sooner you stop the faster your body/lungs start to feel better. Go for it. Be in control of yourself. You're the boss.
