I gurrently have 6 cartos of differnt flavors 4 tanks, and 3 Clearos all with different flavors. They are all mounted on batteries which I rotate to charge. I am constantly going from one flavor to another round and round. Its like a lazy susan of flavors. I can't find just one I want to stick with. I like one for a few puffs and then try another and then change again. I mix new flavors and then by a few. juice then ry4 and the back to a cake flavor. Never did this with my Pall Malls. Always smoked the same thing and never gave it a thought. My wife thinks I am obsesed and going a little overboard. Anyone elese struggling with this obsesion? Possibly my ADHD kicking in.
