well, you might consider starting program now with a goal of quitting in 6 months. You certainly sound like you don't want to increase your nicotine intake levels, do you? Do you want to go to higher levels of vapor and high levels of nic, cause you can here. Or you can chose to hold the line and try to start reversing your exposure to nic. We're gonna support your decision, whatever you decide because we know nicotine is a heck of alot better than cigarette smoke. If you want to try to back away of this habit, you might start down low with an 801 style, it's a work horse model. Or if you want to walk on the wild side, a 510 would take you to a higher level of play, more vapor blow, an 801 is a slower, more calming device. When my 801 acts up I'm usually pulling to hard on it. I'm hot boxing it, 801's don't like hot boxing. A 510, if i'm correct, can take more hotboxing and will deliver more vape. I am getting off nic, I strive for a device that I won't become dependent on. I'm on my way out after 35 years of cigarettes. You'll get plenty of advice here, you have come to the right place. What I wrote above is my opinion, other will have their's.....listen up and take your time, make a good decision you won't regret.......vape on bro!
