1. Set even more alarms. Annoy yourself into being awake. Identify when you want to be awake, and start your first alarms at that time. Increase frequency as you approach the time you need to be awake. Make your wake up time harder to ignore.
2. Involve multiple senses. Sound alone isn’t doing it? Add sight, touch, taste, or smell to your alarm regimen. There are several products that can do these kinds of things. For example, I have Home Assistant turn on my room lights to full when my phone alarm goes off, and I could easily add a diffuser, or a vibrator under my mattress. Bonus points if it takes multiple steps to reset your alarm. Which leads me to…
3. Increase alarm reset difficulty. The more you have to conciously engage your brain to reset your room to sleep mode, the harder it will be for your brain to automate the snooze button. Put your phone across the room, use an app that continues to scream until you scan a QR code in another room or solve math problems, make a deal with your partner that they get to spray you with cold water unless you correctly answer these riddles three, anything. Make it difficult for your brain to remain in sleep mode when your alarm goes off.
4. Enlist the humans in your life to help. Ask, cajole, or haggle with your parent, partner, sibling, roommate, friend, or whoever else you’ve got available to help you wake up. Be it pleasurable reward or punishing annoyance, whatever they can do that is hard to ignore and can get you going will be better than one phone screaming into the void.
5. #4 part 2: Involve medical professionals. Sleep is a process that involves your body, and when your body isn’t working as you expect, you take it to the Body Shop. If nothing is working, talk to your doctor about your struggles with waking up when you want. They can help you narrow down the root cause and supply treatment if necessary. This treatment can range from sleep hygene coaching, to OTC medication recommendations, to prescription medication addition or adjustments, or even doing a whole-ass inpatient sleep study to figure out what’s going on. If nothing else is working, present your problem to a licensed Professional Human Animal Mechanic.
6. Don’t give up. This is a problem that can be addressed. It may take adjustments to your life that are unusual or unpleasant, but remember that, just like exercise, you are trading one unsustainable unpleasantness (i.e.: employment problems due to chronic tardiness), for another sustainable unpleasantness (i.e.: going to bed earlier, or changing your sleep environment)
