I rolled for the first time a few days ago. I took approximately 200 mg of molly at once. I did roll, but not much at all. I'm unsure of the reason. It may have been because I'm 6'2" and 280 pounds or because my friend who was rolling was annoying the hell out of me. Would these factors contribute to a less noticeable experience? Would it be safe to take a larder dose, such as 500 mg, at my size?
