Ever since I got a new setup, I've been feeling weird lately, like getting a little nauseous and gassy. I was using an aerotank v2 on an ipow 2 with 18 mg juice and I just currently switched to a subtank nano on an istick 50w using 70 vg 30 pg with 3 mg nic. Am I feeling this way from the sudden drop of nic I'm used too? Thanks!
