I just joined the forum so that I could make this post. I've been watching the forum and
vaping since early February. I was using 4mg nicotine - yes, super low nicotine. Apparently I went overboard one day, because I woke up very dizzy and had some dizzy spells the next day. It also was hurting my teeth.
I stopped
vaping right then, and ordered 0 mg (menthol) liquid. That solved the problem. Someimes I mix it 2 to 1 with the 4mg. I don't seem to miss the nicotine (just need that
throat hit). I'm concerned that so many people on this forum are using such high levels of nicotine. It's scary enough inhaling an unproven substance, let alone the possibility of nicotine overdose.
So, I recommend going with the lowest nicotine level you can handle.
