i dont know why, but recently vaping has been very frustrating... i cant seem to get it right! this is my 9th month vaping, and for the last week my set up is not performing like im used to. i use the vivi nova mini for a long time with no problems, but now its clogged feeling and i get a bunch of dry hits and very poor flavor! have tried cleaning, replacing the heads and even purchased a new one. nothing works, and i even switched to an atomizer and its just not right??? i have a provari mini, im thinking something might be wrong with it? but that doesnt make sense? please help! before i go crazy. thanks
