3-4 hours is unhealthy. insomnia is being super tired all the time and not being able to sleep, it's not that you don't need the sleep, you just can't get it, you are still groggy and irritable and slow.

instead of trying to sleep less, how about you work on time management throughout your day and become more efficient at doing all the things you have to do. make a list and triage it, determine what is most important, down to what can be put off, see if you can combine tasks, etc.
