Figured out my nap alarm was the issue this whole time
For months I set my phone alarm for 30 minutes and kept waking up groggy, so I assumed naps just weren't for me. Then last Tuesday I forgot to set any alarm and woke up naturally after maybe 15 minutes feeling great. Turns out I was sleeping through the light sleep stage and hitting deep sleep, which made everything worse. I switched to a 20 minute timer with a softer chime sound and it's been night and day. Anyone else find that the alarm sound or length changes everything for them?
