Well day 1 here and I have had a nic buzz all day. Started out with a 6 mg low cart. It wasn't satifying my cravings so I uped it to 12mg. Well that's when the buzz started, I haven't vaped alot at all either. I am still on the same battery (510) since 2 pm. I did drop back down to 6mg and Im still buzzing alittle but it's not as bad as it was. I was a 1/2 pack to pack a day smoker. I find it weird how low a nic level I have.
