How weird. Woke up at 5:20 AM feeling hungry. Not awful hunger pangs any more but hungry enough that I was not able to fall back to sleep.

had a glass of warm milk

Spent some time in bed. Realized it was not enough. Had another cup of milk.

Was then drifting in and out of sleep while listening to very unusual Italian fairy tales. Ultimately got up at 9AM, alert and refreshed. The BiPAP machine showed 10 hours of usage. Oura showed nothing: again I had forgotten to charge it, darn.

the funny thing, at 7AM I took amphetamine, but it did not wake me up.

At any rate, I will make the most of my day today and will eat a heavy meal before bedtime hoping I won't wake up hungry at wee hours in the morning tomorrow.
