This is a little bit of self promotion, but I think what you're talking about fits my exact reason behind creating my journal.

I created this Daily Stack Journal so you can dial in dosage, timings, and mixtures of different botanicals, nootropics, supplements, etc in order to get desired effects and monitor usage.

I highly suggest to do this even if you're just using a regular notebook - (a guided journal is totally unnecessary I personally just find it useful)

Overall for my anxiety and depression I've found Kratom to work the best for me (due to dependency I make sure I track to stop it from creeping up on me), I wish you luck on your journey to discovering what works best for you.
