my sleep schedule is totally messed up

[M1NT]

It's very pleasant to be up at 3AM

To still have a normal sleep schedule, just go to bed slightly earlier than 8, or alternatively "start a new day" without sleeping (When 7-8 am comes, fix some breakfast and wear new clothes).

is that really sustainable though? is that what you do?

You may have DSPD

thanks bro, that was helpful. this is the first time ive ever heard of that before

Same, I fixed it somewhat

what did you do to fix it somewhat?
