Recent edit to Methylphenidate
Hello, and welcome to Wikipedia. I noticed that you removed some content from Methylphenidate without explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an accurate edit summary. If this was a mistake, don't worry; I restored the removed content. If you would like to experiment, please use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you!
