Does this sound like the set of challenges you might be facing?

• I drink coffee into the afternoon and swear it doesn’t affect me because I fall asleep just fine
• I drink coffee into the afternoon and figure it’s fine because I still fall asleep okay
• I’ve always assumed my afternoon coffee is fine because I fall asleep okay, but my sleep is shallow and I get that nasty crash, and I want to actually grasp how long caffeine lingers so I can do the math instead of guessing by feel.
• I fall asleep fine but wake up feeling like I never really went deep, and I’m starting to wonder if that 3pm coffee is still working in me at midnight even though I don’t feel wired.
• My afternoon coffee gets me through the slump but then I sleep badly, wake up more anxious, and reach for even more caffeine
