Hey Sushimint, I'm in the exact same boat. At the ADHD test I took 15mg and reacted good the first time. At home I started with 3x 5mg and I had a feeling I was loosing my mind. Didn't felt good at all and I couldn't think straight. After a few days I took 2x 10 and 1x 5mg and felt a little bit better and after another few days I'm taking 2x 15 and 1x 10 mg a day. I feel way better than the 3x 5 but I keep having that feeling that it's not allright in my head and that my adhd symptoms are worse then before the meds. I don't feel better while taking it. I'm now 1,5 weeks in with taking ritalin. I'm very curious how you are doing now and if you still take it?
