I didn't drop my nic gradually at all, I needed whole tobacco and that was a gradual transition, but after I finally did that I cut back a little until after maybe I month it dawned on me that pure nicotine doesn't satisfy and agree with me, even cigs had too much, and basically halved my mg level overnight. Now I've kind of hit a lower limit, which you may be close to. I use 1.5 mg at 14 watts on my rda mostly and 6 mg at 5 watts (I don't exceed 5.5 watts on Protank 2/EVOD 1s). This is enough to add some throat hit and nic effect. I like the vaping more at higher levels, but it doesn't agree with me. As it is, I could use vaping a little less, and that's starting to happen by itself.
