Well, you should get roughly 7~8 hours of sleep so you go to bed around 11pm. Thankfully I don't have any issues falling asleep.

If you slept in a lot and have a few extra hours in the bank, you could push that 11pm to like 1am or so. Just try to return to a normal sleep schedule ASAP.

I wake up at the same time every day. I usually go to bed around 11pm and wake up at 6am. Even if I go to bed a little later, like 1am or go to bed sooner like 10pm.. I still wake up at exactly 6am. Once you do it long enough, your body just wakes up naturally. I always wake up a couple minutes before the alarm.

People really shouldn't sleep in excessively on the weekend. If you have a healthy sleep schedule Mon-Fri and then go to bed at 5am Friday and Saturday night.. you're essentially undoing all the healthy sleep habit you build during the work week. Sleeping in a little is OK.. so instead of 6am wake up 7:30am or something.

If the problem is you can't fall asleep, there are the common tips. No screentime an hour before. Try reading a book in bed, that always puts me to sleep within 30 minutes. It's easier to sleep if you're eating healthy and exercising. Increase your A/C so that it's around 70 degrees F and get under the blanket. And if you just desperately need to sleep because tomorrow's an important day then I don't see a harm in taking a benadryl. Just can't make a habit out of it.
