I have had my Riva-t for a few days now. I am really pleased with it so far. I am using a ce-6 clearomizer and was wondering if I need to empty it out every night before bed. I have filled it up daily and at the end of the night I simply just put it on the charger. It seems to simple and I feel like I should be doing something else to it. Am I suppose to do anything special after a day of use? Or is it that easy?
