Cutting Computer in Evening

I have recently managed to restrict my eating period to about 8h per day, which is supposed to help circadian rhythm. Yet, to further promote sleep and circadian rhythm, I should also cut out blue light from a computer a few hours before bed (and go to bed at the same time each day). Since I get *bored* when I cut the computer at this hour, I always revert to using the computer, delaying bedtime in the process. **What would Buddhism suggest as solution towards such a computer use?** In the evening, I'm unable to find activities interesting enough, I always revert to using the computer. Would avoiding the computer at *other* times decrease my attachment to it overall? What might help?
