Pink swayers - How much coffee?
Since you don’t regularly drink coffee, maybe you’d only need 1 cup to add to your sway to be more pink friendly...? It would be 1 cup more than you haven’t drank previously, and 1 cup is likely more manageable than 2 or 3. You may even get used to drinking 1 cup of coffee to be able to drink it at 2pm and not have it affect your sleep.
As for helping you sleep, even for just tonight, the only thing I can think of would be to have a relaxing bath with lavender, get your pj’s on and go to bed early.
Oh and to help with your eyes stinging, keep your eyes closed even if you are just laying there. It will help your eyes feel more rested even if you aren’t in a deep sleepy. If you can try to breath deeply and slow your breathing as well, you may actually fall asleep.
