I was so excited I got my Ego today!!!! I got everything out of the box (I watched all Dr.V's videos yesterday), read the directions and wanted to get started. The first time I vaped, I ended up with a bunch of E liquid in my mouth (gross). Tried again, E liquid in the mouth. Switched over to the second unit, same thing. Obviously it's something I am doing. I just used the automizer/prefilled cartridge method. What am I doing wrong???
