You know, It's interesting. Since I have been vaping liquid nicotine i have discovered something cigarettes did not do. To me this is so much better than a calming effect and that is the raw stimulant effect of nicotine. I LOVE it. I don't want it to calm me down. I use it to speed me up. I can get this effect at 18, 21 or 24 nic. Only e-cigs do it. I noticed it when I like our Op vaped like a research monkey and found myself having trouble sleeping at night. It's defiantly like a caffeine buzz. I'm a coffee lover as it is even in the summer and this effect is stronger than caffeine. I had read that nicotine was a central nervous system stimulant but really never felt it's true effects til I started vaping. That kick is for me.
CigarBabe, just read your post.
To solve my sleeping at night problem I had to cut back on nic levels at night. Perhaps some WTA would help with that. So in an e-cig, I can get my uppers and my downers LOL I think I'll give it a try.
John, the calming effect I speak of is related to hyperactivity and depression. (mentation related). The calming effect is directed towards the brain. Regular e-liquid did nothing for me. Nicotine can have different effects on different people. I get my energy boost from mucuna which targets my dopamine receptors.
