Try delaying your first caffeine intake of the day until 90 to 120 minutes after you wake up. Your afternoon naps might just disappear, mine did. If you can't go straight to 90 minutes just work your way up in 15 minute increments over a week or so. Look up the Huberman Lab podcast episode on caffeine, very informative.2 coffees per day. One is first thing in the morning, and the other is mid afternoon. Just black coffee. Rarely drink alcohol. No nicotine at all or other stimulants.
