One-page tracker for compound noise and side effects

I keep a one-page tracker, not a reference guide. Columns: date, compound, reason, appetite 1–5, sleep hours, GI flags, resting HR, and whether I’d repeat it. I update it Sunday with my 10-day weight average. Last month I was sure a peptide was driving 3 a.m. wakeups; the log showed those nights clustered after late cardio and two drinks, not the compound. That killed the urge to add anything new. It’s not anti-peptide. It’s anti-vibes. The tracker only earns space if it changes a decision, so I’ve cut fields that never did. If you keep something similar, which columns actually earn their keep?
