I've been vaping for about a week and a half now. I got a cig2o and love the flavor of their tobacco carts that came with the kit. It's difficult to get cartos from cig2o, so I ordered some sample packs from vapor4life. I couldn't believe how fast my order came in!!!! So far my favorite is the 555. I still crave analog every once in a while. (I don't understand why, they taste nasty!) I let myself have one every so often mainly to keep from stressing. Only had 4 today!!! Most of the time when I crave an analog, it's during stressful times. I was thinking about getting a higher dose of nic for those times. Anyone tried this?
