Try one alarm not on the full hour but 3 to 5 min late. This makes you feel you have to get up because it's your only chance and your buffer is already gone so no excuses.
Also loud and out of reach so you have to get up to shut it off

Not FOSS, but the one that got me to let go of Nova was Octopi Launcher.
Very close to a drop in replacement, brings most of the features and customizability that I got very used to.
