I know that feel... I used to hate ce2s as well.
I don't hate them anymore, but they will never be something that I can use all the time. They don't hold enough juice, and can leak easily. But here's how I use them.
Remove every silicon gasket, ring, etc. from the ce2.
Fill up the ce2 almost completely, just under the ceramic (white) cup.
Put the middle ring (should have a side that has ridges of sorts) facing the coil/cup.
Put on a drip tip, hold the ce2 upside down and see if it starts leaking (if it does, adjust the silicon gasket)
Give it several primer puffs, putting the ce2 upside down to force it to wick.
Take a nice drag, and enjoy.
I hate them towards the end of their fill, no matter what I do it wicks like crap. I take incredibly long drags (10-15 seconds, followed by another 5-10 seconds for extra throat hit) so it's probably me. I'm still searching for an atomizer that can handle my drag time, till then I'm a carto fan.
