I usually top off w/3 or 4 drops about a half dozen times or so if I'm sitting around puffing the thing all day. I've smoked the KB almost constantly, but that's with lower juice.
As for your comment Rusty, you're a bit off the mark. I used to smoke (about 3 years ago) and walked away from them with no problem because I didn't like the effect on my lungs. I certainly don't intend to demean anyone because I think it varies from person to person, but IMHO I think that "needing" nicotine is simply a state of mind. I did not suffer any withdrawl symptoms nor did I ever relapse with analog cigs. I enjoy the feeling of a nic "buzz" and now that there is a way to get that without getting winded after a few pull-ups, I'm simply taking advantage of that. If I forget my ecig at home when I go out, I simply have the self control to wait until I get home...it's not a big deal for me. If I start to experience any shortened endurance as I did with analogs, I'll simply give quit and give my devices to my wife who would still be smoking regular cigs anyway if not for these.
Way to judge though, I'm impressed.
You are one of the lucky ones. I have been smoking 30+ years and am a total nic addict. Managed to quit a couple of times but give me one cig and you might as well give me a carton because I'll fall off the wagon. For me it's all or nothing. E-cigs give me an option because I can have my cake and eat it too, all and nothing so to speak. It is not a matter of self control. More a matter of brain chemistry. Others definitly suffer withdrawl. I have actually dreamed of smoking when I quit. Just consider yourself lucky. The comments are more a concern for you than a criticism.
