Molly tends to make me sleepy, and I seem to have good experiences in the past with pills that have tested to have both MDMA and caffeine in them on ecstacydata. I plan to drop 175-200 mg of Molly (tested good) and was wondering if it would be okay take some vivarin or no- doz along with it, like maybe the recommended dose to stay up for 4 hours or so. I know the Molly can be hard on your heart and don't know if the caffeine would make it worse or even dangerous. Also most likely will be taking levitra before the comedown hits so I can have sex with my girlfriend. I know definitely levitra makes your heart work harder but it's the only way for me, just cannot get it up while on MDMA. Anyone have any caffeine tips?
