I started using pv's back in Oct., However, when I caught a cold in Jan. I couldn't tolerate the vapor and went back to analogs. Now I'm using both. I really hate cigs but they offer a quick release of nic cravings that I can't get from pv's even using 36 mgs. Does anyone else do this or am I just weak willed. I'm 63 and have been smoking since 15.
