This sounds like standard reaction to ADHD medication for someone that has ADHD, and usually point where you fiddle with the dose and release-mechanism with your psych, untill you get best results with fewest drawbacks, modulo pareto efficiency and all that.

But if you managed to accomodate yourself to just be able to actually rest to a usable state ... more power to you, and I would like to hear more!

I do have a feeling that if I exercised daily, and slept well for 8 hours every night ... I might not need that boost from those meds. But the meds do keep me more organized so that I am actually managing at least the sleep thing? Unless I take them too late? Trade-offs everywhere :D
