I smoke Pall Mall (red/shorts) for almost 10 years..about a half-to 1 pack a day (never went over a pack in a long time)..and if I did (when I used to work at a nightclub for 11 years--I STILL never got any side effects from "nicotine poisening")..
However, I just started vaping...and got the 510 ecig (from Vapor4life--wonderful cigs)..and thought 11mg would be just fine enough to "chain vape/smoke"...and then about 30 min later (after chain vaping for an hour on 11mg--never finished the cart)..my heart started racing...

I DID tho--have 2 cups of coffee that morning and 4 analogs before that)..although never got sick or felt sick..that freaked me out...now I'm scared to vape...although I do have some good 0 nicotine)...I am constantly depressed for the past week about wanting to "chain vape" (I stay at home and work online)..and is too darn scared that I will get nic poisening if I do that!!
Again, didn't have any other side effects (not even a headache) after that chain vape..(although my hubby said most likely my heart just raced a bit..but then gave me a panick attack)..but I don't think so..maybe a bit of both (and I never get pannick attacks--the last time I did was when I was taking some diet pills a long time ago--will never do THAT again)...
I found myself vaping 0 nicotine..but still reach for the analogs (and really don't WANT to

...but I want to be able to smoke the way I did before---which (I know, bad)...I chained smoked in the mornings...for a few hours while working online ...but now I'm so scared I won't be able to do that..even tho I have some 8mg of nictoine..I know that is considered low..but after reading about even my full flavored analogs (Pall Mall Reds), have about 1.7 mg of nicotine in EACH cig...which means it takes a WHOLE pack to get about 30mg a DAY (no wonder ppl buy so many packs, or smokes so many--possibly WHY tobacco companies make SO MUCH--by putting only a tiny bit of nicotine in their cigs to make us buy more and more)--which is fine..however, will 4mg of nictotine be ok for me to chain vape? I do know (or read), that 20 drops is about 1ml of nicotine from the actual bottles...so if this is so...I found one of my wonderful vapers (Inferno from Volcano ecigs.com), lasts for about 3 hours with using just 3-4 drops..
Sooooooooooo..(sorry I am a newbie to ecigs..lol)....does this mean that vaping on 4 drops of 4mg nicotine every 5 hours is ok for me?
I know you all say it depends on the person, health, and the amount of types of cigs they smoked before vaping (I'm 31, in great shape--I work out about 5-6 times a week and do weight training), and I eat VERY clean too. I'm am a health nut and have no health issues (except yes, smoking cigs for the last 9 years)...
