^^^ couldn't of said it better... it all depends how the serotonin in your individual brain is... I know my good friend shouldnt be rolling more than once or twice a year with how depressive he can be, as a relative is as well... i personally refuse to roll without waiting at least a month... this way i know im being a bit more healthy with my serotonin usage, and it makes my rolls that much better... i strongly stand by spacing it apart, it makes your night that much more epic... dont just roll to roll, roll at an event, or a special night.... thats what it should be for in my opinion... never just for the hell of it, the night should have meaning.
