Yep, I've got three tanks going too-PeaceMaker, Beach Bum and Chocoalate (all 18 mg.) I had Wowboy in the Chocolate tank, but after a few days it kind of ruined the flavor of the Beach Bum for me. I like Wowboy, but after a few days of it, my taste buds needed a break from it. I tend to alternate vaping from all three tanks!
