My wife says she has numb lips and tongue when she vapes anyone hear of that before? She has been vaping for 4 months and she still smokes about 10 cigs a day. She is using a combination of mints and cherry tobacco using a EGO and vision clearomizers. I gave her my VAMO and Vivi Nova tank this week to she if that changes the draw she is doing. Maybe that would help. Anyone?
