Waking up a little early - how to disable impending alarm

Sometime I wake myself up about 30 minutes before my alarm due to nerves about the day ahead. Today was one of those days.

It is a shared bed scenario, so I’m leaving someone behind in bed when I get up.

I’ve made a habit of setting an alarm on my phone to come back and wait for alarmo to go off so I can silence it.

Am I overlooking some other way to manage this scenario?
