I tracked six weeks of 'my meds stopped working' — turns out it was my sleep. Data inside

I owe my psychiatrist an apology and I'm posting the receipts. Week 3 of "my methylphenidate stopped working" I was drafting the ask-for-more-mg speech. Instead (procrastination win??) I spent six weeks logging sleep from my watch, dose times, and a daily focus score out of 10. The pattern is humiliating in its simplicity: every single "meds are useless" day followed a night under 6.5 hours. Every 7.5+ night, same dose, worked fine. That's it. That's the whole mystery. Posting because "track it before you change it" would have saved me a month of spiraling. But also genuinely curious — can sleep really swing stimulant response THIS much, or did I just get lucky that mine had one obvious variable?
