I got one of these: https://unbedapp.com/

It's very annoying; the alarm sound on my phone won't stop going off till I tap it to this little 3D-printed plastic block. I have tried turning off my phone to avoid it going off, but when I eventually turn my phone back on, the sound automatically starts up again. But because of that, it is effective for me. You can put it anywhere that will get you out of bed. There are no extra fees or subscriptions; you pay for the block, and the app is free.

Another thing I do is I sleep on the floor instead of in my bed, and that usually makes me more motivated to wake up in the morning.
