I just started generic Focalin 5 days ago, 5mg once a day. It makes me feel wired, like I've had too much caffeine. I can't tell yet if it's helping with my concentration, and it doesn't hurt my mental state as far as I can tell, but I'm wondering if this physical jittery feeling will fade over time. I can't imagine feeling wired like this every day.
I haven’t developed one yet after 3 years on ritalin. Still 20 mg under my daily mg per kg limit so I have room to go up if I need. I take it every day as well with no breaks. My psychiatrist said that he likes to start people on ritalin because it’s less strong so if people develop a tolerance they can go up to dexamphetamine.
