Does anyone have any experience with this stuff? A buddy of mine with ADHD gave me them (he's prescribed them) and said they would help me focus on school and work better. He also told me if I wanted to have fun with them, to try dipping them in water and rubbing the first layer (white) off until all I see is a container of pink on one side and brown on the other (kinda like neopolitan ice cream). He said to cut down the center of it and try taking one side at a time and see how I feel. What exactly is the pink, or the brown and what are the precautions of the aforementioned?:confused:
