I started out at 24, quickly realized that was too high for me and moved down to 14. About 6 weeks ago when I started DIY I dropped to 12mg and now find that if I vape any higher I clench my jaws so much that it makes my face and head hurt.
I had a small DIY mishap last night and it reminded me not to take safety for granted. I usually wear surgical gloves when handling my 60mg nic concentrate, but got lazy and skipped them. Well you guessed it...I have never spilled so much as a drop, until last night. Got a small spill on the mack of my hand and within 5 minutes I was sitting with my head between my legs from dizziness. It passed fairly quickly...but don't take short cuts with handling nic concentrate!
