yikes, I just bought a new mod and the nicotine delivery is so much better quality than my original eGo that I almost had a panic attack from all the nicotine in my system by yesterday evening! Time to lower my already tiny dosage from 4mg to 2mg. Can't believe how sensitive I am. Anyone else experience this after upgrading? I am new here and new to vaping so was not exactly expecting this hah. Only danger of vaping so far: the vape works too damn well
