With my Ego C and my cheap clearomizers I've been vaping 24mg nicotine e-liquid. Yes, that's high, but I was kicking a 40+ year cigarette habit. I recently purchased an eleaf Istick 30w (which I love) and a Kanger Subtank Mini which should be in tomorrow. It occurs to me that with more vapor production I will need to dial back my nicotine. My question is...how much? Should I dial it down to, say, 3mg and bump it up if necessary? I know it's subjective, different for everybody, but any thoughts...rules of thumb? I'd appreciate your input. Thanks.
