I'd start off with 18mg of Nic in your flavor(tons to choose from at your local vape shop or online) and if that don't give you the kick you need go up from there to say 20-24mg of Nic or until you find a level of Nic that's right for you. I'm at 0nic just flavoring but im like you I like the act if smoking my main stressed to start the ecig is cuz I had to stop smoking marijuana because it was effecting my meds. So I started with a low Nic of 6-8 and weaned my self off to 0nic
