I was getting nic brain freeze, so I went down to 6mg for a few weeks and found I was constantly
vaping, walking down the street, sitting at my pc. I just felt I wasn't getting enough nic. I don't feel comfortable with it, it's a bit too compulsive, and I always feel a bit tense.
I'm going to try upping my dosage to 9mg, at least where I can put the pipe down before I get a headache, and still feel satisfied. It's a fine line.
Getting the dosage just right is the hardest thing.
