As a senior, a former nurse, and a fallen Catholic, I found one bit of advice that works well to cover just about everything one encounters - mental, physical, emotional, spiritual, and yes - even medicinal. I'll share it with you here -

All things in moderation.

I take a shit-ton of medications & have for much of my life. They allow me to breathe & function at a pretty high level. But all meds have side effects so - I take what I need, but no more. No less - but no more.
