it could be the shock of waking from a deep sleep with a shocking alarm gives you a blood pressure smash or something. maybe try a softer alarm method, like a light fades on, or a fan turns on etc. how terrible is your alarm?
or it could be you are thirsty or otherwise suddenly aware of an ongoing pain that you weren’t conscious of while asleep. is your tongue sticky when you wake up?
