haven't read this anywhere yet, figured I'd offer it up to anyone who does cartomizers
when you're topping one off, put a condom on the battery end before you fill it -- and the juice starts to pool like the filler isn't sucking it up as fast, just create a seal with your lips and blow into the cartomizer a little and unless it's really full already you should notice that the top of the filler looks dry and ready for more liquid
just a little tip -- some people put the cartomizer in something and sling it around to use centrifugal force to work the liquid down toward the battery end, some people shake it up -- but I've found blowing in it really works great for topping it off
