also you can remove the atomizer, place a napkin at the drip tip and gently blow through the 510 connector to help get some of the excess juice out. If you are using a tank, at night place it upside down might help keep it from flooding overnight.
lol you'll get lots of replies about best juice
but I will say that madtown vapor has never let me down
fuggin vapor is another good one and often has sales on juice
so far I've been impressed with abstrakt and keep an eye out for their deals of the week they often have some really good deals
