I've been vaping 10mg ejuice for a few weeks now and every time I vape for a few minutes I get a tingling sensation and a slight headache in the back of my head. Never had that problem when I smoked analogs. I use a Nautilus mini with an eleaf istick power 80w mod. I decided that maybe if I change my tank and mg to 6 I'd be ok. Went out and bought a kangertech toptank nano with some 6mg ejuice. The problem is the tingling sensation and headache decreases but my nic cravings are more intense. I'm so confused here its not funny, so what do I do? Should I stay with the 6mg or go up to 8 or something and see what that does?
