So obviously it might be a medication/dosage issue, we'll take that as considered.

If you're new to medication you might find that you have problems like you describe not because of the medication exactly, but the way you're used to regulating yourself is maladaptive, and coming out as the need to be doing things.

It's obscenely common for people with ADHD to get by with anxiety or unhealthy thinking patterns replacing the neurotypical drive to do things. This works for a time, but now you have the ability to actually do things, you feel like you need to do them ALL THE TIME, because you're actually capable of that now. But that comes with a nasty cost, which it sounds like you're well aware of.

It might be worth spending time with yourself to relearn how to relax whilst medicated, how to keep in contact with your body and energy levels. A psychologist might be helpful if that's an option for you. It's also important to maintain regular usage of what medication you're using at the time, as you'll need to let your body become used to it. It takes some effort, some getting in touch with yourself, some honestly about what you and your body needs, but it's very possible to achieve a balance between productivity and health.

Also, remember to be gentle with yourself. You're adjusting to what is widely considered to be a disability, it's not fair to expect perfection from yourself. Just keep attempting it over time, you'll get there.
