Great dedication to data gathering!

It would be easier for me to visualize if the color scale were simpler and more directional (this one goes back and forth to my eye). The greys in the beginning and purple at the end blend together when I look at this on screen. That obscures where there are highs and lows. If it went white to black in one direction it might be easier. Rainbow is good for these too, but typically red feels like a problem or limit that you don’t want to exceed. You could also bundle some ex: 0, 1, 2 or more per day.

Are you thinking menstruation is correlated? Or are you looking to see if it is? If so, maybe you can rearrange your data to show poop qty trends relative to days before or after period start.

If you’re making your own, try slowly blending in more and more decaf. Maybe start at 25% decaf and increase 25% each week. Later you can use a caffeine free sub and do this again (teechino, postum, chicory, etc)

Then like any other addiction, know that you can be susceptible to fall back quickly. Watch out for it, especially early on.
