I've only been vaping for about 6 days now. When I got my 510 I was amazed at how "cig-like" it felt - haven't had an analog since I got it. But in the last 2 days I've noticed that I don't seem to be getting the same TH. I'm using carts that I just refill; have done the mod where you just trim the fill inside to a smaller length. Do I need to clean my attys? Try dripping? (I'd like to try dripping but have no idea how to go about it yet). I'm using the same 24mg ejuice that I did the first day.
