I used to work 5am to 4pm. Life is shitty.

western countries 5am is different from Malaysia 5am.

Malaysia 5am dark af. some countries can be bright at 5am.

yeah been this too, just need rearrange your sleep patterns

like alot of my friends ever since they got kids also they been sleeping at 10pm and waking up at 6am daily like routine ed, all cause need send kids to school/daycare etc

You have 9 hours sleep?
Sleep so much?

I sleep at 12 wake up at 5am
Auto wake up no need alarm.

You are sleeping too much.
That's why you feel more tired.
Your body is frequently in a state of inactivity.

When you get off work, go do exercises for 60 to 90 minutes.
Take dinner at 7pm and sleep at 10 to 11pm.
You only need 6 to 7 hours sleep.

Another thing to do is to follow the same sleep and wake up cycle even on your non-working days to condition your mind and body.
Over time it will be automatic.

good timing. go out no jam, go home also no jam yet.

Actually not difficult if you are motivated....

I also wake up at 4.40am and back home 5pm, 5 days a week.
Will sleep around 10.30pm-11pm

Been doing this for last 18 years now.

60+ ....  F&B ..I also use to work 3 rotating shifts during my younger days for 6 years.

10 hours .... own business ma ... 

I'm feeling sad too....my new job is 6days a week....Saturday full day! 9.00am to 6.00pm. Yesterday public holiday also need to work...really not use to this environment....

I used to work in Singapore, stay in Gelang Patah

Wake up at 4am
Took first bus at 5:15am
Reach office at 6:30am
Clock in work from 7am - 4pm
Reach apartment area 6pm
Play dota at Internet cafe until 10pm
Go back home sleep by 11pm and continue again

Did that for, 2 years.

Now,

Breakfast 6:30am
Back home around 7am
Work on laptop for a while until afternoon
Pick up kid at 3:30pm

6:30am to 8pm, almost 300 days like this, if off day i sure sleep from 2am to 12pm, dont know why

sleep time is 11:30pm to 6:30am

Resign before its too late...your not early bird type

key thing is must get 8 hours sleep....must avoid using phone or watching TV before u go to bed...screen time will keep u awake.
