Idk I was the happiest man alive when I stopped working in shifts. Granted, in my case the 9-5 salary was better than I had in shifts, but I couldn't handle the irregular sleep pattern at all.
Idk why I'm commenting this since it doesn't seem to have anything to contribute but I guess you do what you like. If you feel you need to take the change for your own health and to be able to enjoy your time outside work, maybe it's worth a cut in salary
