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.
Short answer, yes. You do build tolerance over time and will need to change formulation every few years. When I have changes in medication it takes about 2 weeks to get used to, and I have heard it can take a month or 2 to get used to other mental health medications. Just ride it out for a few more days unless the jitters are unbearable. Remember, you can always talk to your doctor about changing your formulations so feed back your issues so you can fine tune it.
