I use modafinil off-label for focus. I have NVLD, which isn’t ADHD but has some similarities. It’s subtle. It won’t feel obvious like ritalin or adderall. Be careful with it, it’s possible to run yourself down and not notice, because you just don’t feel the exhaustion and you also don’t feel amped or wired. But I think it’s a godsend. I don’t feel particularly different without it, but I couldn’t get it for a while because of insurance shenanigans and I just fell to pieces that I couldn’t figure out how to put back together. I wish I could give a definitive test for knowing if it’s working but I don’t have one. You might have to kind of feel it out. I found I could get really wrapped up in activities that I’d been very frustrated about because of my inability to stay focused. I think it’s easiest to start with small, fun things like a video game you would totally enjoy if you could just actually sit still. If it’s working you may notice that you spontaneously accomplished tasks you might normally find too tedious to stick with. I played Sims a lot at first, and good heavens was my game organized. It won’t fix the avoidance issues you get when you’ve learned it’s not worth it to try accomplishing tasks because they are suffering. That’s something that improves with time as you relearn the boundaries of what you can expect from yourself. Hence starting with easy, fun things and working from there. It’s probably the second worst tasting medicine I’ve ever tried but I’ve had great luck. I hope it helps you too.
