Can somebody build a tank you can hold upside down for when you are laying in bed? Shouldn't be to hard to do. Just reverse the two tank part in something like this http://www.dfwvapor.com/ratank-rebuildable.html so that the resistance wire is in the bottom tank chamber and the liquid is in the top.
Then just add another plastic or glass around the whole thing to put the drip tip into.
