So today is my first time vaping and it's ok so far.  I am noticing that my 510 almost seems to have too much TH.  Right now my mouth and lungs just feel a bit dried out.  Some pulls are smoother than others, but most are kinda harsh.  I'm not sure about the ingredients of what I have, but I ordered some Dekang Cool Menthol 24mg...  Maybe the 24mg is too much?
