Honestly, I vape 36mg and do fine. Its more about the amount you vape vs your nicotine content. If you're a habitual vaper and prefer to chainvape all the time, go a little lower or temper yourself a little until you find a happy medium.
When vaping if your head starts to hurt, set it down and take a few deep breaths. It'll normally go away in a minute or two. If you keep pushing you'll get a pretty bad headache that lasts a while. A little care and listening to your body and you'll get used to regulating your intake, and eventually you just won't like the taste of the analogs anymore.
One other thing I've noticed.. If you smoke too many analogs after being more vape-oriented that itself can build toxins you aren't as used to up in your body and will cause varied symptoms of an unhappy nature. Just try to slowly cut back, maybe go a day without ciggys and just vape, have one with your morning coffee, then one day try with vape and coffee. Eventually you won't be going out for a cig at all. You'll just come on here, sip your coffee, and vape like a madman. (what I'm doing right now)
