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.
If you medication makes you feel uncomfortable, stop taking it, either you’ve got too high a dose or your body isn’t agreeing with it. Your specific symptoms correlate to an adhd meds overdose. Get with your doctor abd talk about it as soon as possible.
