Hello. I'm relativity new to e-cigarettes (about two months). I'm now wondering if I should get a higher nicotine amount. I'm going though about two carts a day and don't know if it's me or the carts. I don't feel much kick and find myself burning through the carts at to fast a speed. I'm worried that if i get a higher amount I will become more addicted to nicotine and depend on it more. I'm not trying to quit just not wanting to become more addicted. I was a pack a day for over ten years. When I switched to the e-cigarette I was (and still) using the 18mg nicotine. I found myself getting a little light headed when I first started but that quickly passed. I think I was just overdoing it (new toy syndrome). What do you guys think? Is it a risk or am I not getting enough to start with? -Thanks for the help in advance.
