Isn't that funny how that works. 12 mg is now too strong for me but 6 mg has me vaping all day. I would rather have the lower nic but I find I go through so much more juice. If I use the 12 mg at night I cant sleep at all. If I use the 6 mg and don't vape a lot I start thinking about an analogue. You would think that after all these months I would be done with analogues but thats not the case.I used to smoke 12-14 very long 120s a day, and when I replaced smoking with vaping, got by with 1 carto a day. But then I got into vaping a lot more than I smoked, so now I'm up to about 4 cartos a day. But I've lowered my nic strength way down since when I started. I think I'm more hooked on the flavors now.
As for carts I find the constant refilling to keep them wet enough for my tastes is a hassle. I love the vapor of the Nanos but since I go through so much juice I would have to refill like 5 or 6 times a day. I had stopped using clearos and moved to Ce3's but the number of refills was a pain, especially with the CE3's.
If I was new to all of this I would say use the Nanos if you are using a 78 and use the clearos or Nanos if you are using an X2 then when the T3 comes out switch to that. I just don't like how long a cart lasts for me. I was smoking ultra lights, just under a pack a day, but I guess I suck too hard and they just seem to start drying out too fast for me.
However, carts/cheep gas station ecigs got me to quit but its SI that kept me from smoking.
