Did for a few years. It's a pretty crazy drug. Went through a really long evaluation and testing then doctor prescribed, more than many I know. I went from a C student to an A- student overnight. My social behaviors were impacted, but I ate like crap and slept like crap, with excessive nicotine and energy drinks. So hard to say how much was from drugs or not. I've thought about writing a blog about this. Perks - Lost tons of excess weight and tried to keep a little bit of muscle - Crushed exams, studied hard - Did so much better at work - Emotions and anxieties are basically gone Cons: - Lost muscle, lots of it, just finally getting it back - Overstimulated socially, sometimes miss social queues and often caught staring at people - Easy to neglect things because nothing matters except the task your doing I started only taking it during weekdays, but it was the only thing keeping me in good academic standing at the time. I still don't think I would have passed without it, even with what I know how and my behavioral training to combat adhd.
