Trippin' Through Time

I've been there. I know what you mean, but also, you're essentially confirming what I'm saying. You've trained yourself to sleep through them, which is why you need 8. The problem is that you're just increasing your training and making it harder and harder for yourself to wake up.

When the first one goes off and you snooze it, and go back to sleep, your body tries to start a new 3 hour cycle, but then 10 minutes later your next alarm interrupts it. That's what that heavy, groggy brain fog is. It compounds with each alarm as well.

If you do this over an hour, you're also robbing yourself of an hour's worth of good quality sleep.

If you want to fix this, cancel all your alarms except the last one, and put your phone somewhere you have to get out of bed to reach. Disable snooze completely. Snooze is the enemy. Also, set a new alarm tone as your current one is now useless.

You can also get a cheap smart bulb and have it fade in to full bright at the same time as the alarm.

I also found it useful to use a Playlist or radio alarm clock.

Going forward, routine is your best friend here. I know it sucks, but stop sleeping in on your days off, and go to bed as close to the same time every night as you can.
