I was diagnosed with ADHD when i was 5 years old. I would take ritalin, all the time, til now. As far as I can remember, i would alwasy get side effects: nervousness, anxiety, loss of appetite, insomnia. As i got older, the side effects got worser. So in 2006, I started taking Adderal XR, and it worked, but the number one major symtpom that i got was anxiety/nervousness., and of course accelerated heart beat. When im on this, im calm, im so concentrated in my work, that i lose interest in the things that i like to do. Anyways, idk its its psychological, but sumtimes when i take ritalin, i get anxiety/nervousness, accelerated geart beat, till like maybe 12 in the afternoon, and then at other times i dont get those symptoms. What's the deal?
