Do you have a day where you can plan to just sleep without the alarms? It sounds like what we experience when we're burnt-out, and a day of uninterrupted rest helps a ton, when it's an option.

I have a few suggestions, as someone with insomnia here’s what was recommended for me. Not all of them worked for me because of my physical disorder but it tends to work for others. Placing your phone or alarm clock across the room where you have to get up has been proven to wake someone up since they have to sit up and then stand up. Also it could help you get out of bed and it was recommended to me after getting up to take a lukewarm/cold shower since your already standing or to splash your face with some cold water. This is just a suggestion though it doesn’t work for everyone.
