Yeah, nicotine is a hell of a drug. It is best to get it out of your system and keep it out.
When I vaped, prior to quitting, I think I was actually consuming more nicotine and taking more puffs than with regular cigarettes. I think not smelling like an ashtray gave me a false sense of security but I would get sharp headaches on occasion when vaping that I did not usually get from regular cigarettes. There are likely a lot of health issues that have not been discovered yet from vaping.
You've done this before, though. Time to put nicotine behind you once and for all. You can do this.
**Also, I second what @Reciprocity said. The NOPE page can be helpful if you think you may be interested. Just pledge to make it through the day without taking a puff and worry about tomorrow when tomorrow comes.
