Has anybody ever have this happen to them? Its like a weird tingling sensation on the top and sometimes back of my head. Is it my nic level maybe? I use 12mg and I've read online and on other forums it could be that maybe my nic level is a little too high? Is this true? And if it is should I drop my level down to 10 and see if that does anything? I've only been vaping for a little over a month now. And it started about 2 weeks into it.
