I couldn't have made it without my tank system, same goes for the wife! She was ready to go back to smoking because of all the headaches involved until I gave her an ego tank. Everyone is different as well. I smoked between 3-5 packs a day, and my wife smoked less then a pack a day. I VAPE 24mg, she couldn't do it without 36mg, of course I also go through between 6-10 tank carts a day, and she goes through 3 a day, I also still have a Joye 510Mega that I keep filled with 36mg nic for those times I'm craving, being a complete and total ......., or its Tuesday, I found that throughout the day it really helps me to VAPE the 36 every couple of hours or so, I think I go through maybe 2 Mega carts a day, and one ego tank cart a day of the 36, but I haven't smoked in 34 days, and for me that's a miracle! I had about given up on quitting, just didn't think I would ever be able to do it. I'm so glad I was wrong. Welcome to the forum, and to vaping, and I'm so glad that it has gotten easier for you, I've also found that the forum has been as instrumental to quitting as the PV'S have been. You have to give it away to keep it, and by your pic I see you like free to, so give your knowledge away to anyone, and everyone who will listen. It's life and death to some people. I found out about it through my wife, from our tigons teacher, she is a vapor, and turned us onto it. She saved our lives! Good luck! And welcome again.
