Day 5 of quitting Seroquel, Is this Normal?

Been on 6-8 mg for 1 year after quitting THC to make it easier to quit and ease off at night.

Overtime knew I wanted to quit this, had some trouble tapering and ended up back on 6mg.

Decided eventually call it quits completely, first night slept 1 and half hour then could not sleep till 10:45 am eventaull slept up until 1:45 pm. So approximately 4.5 hours ish.

Second night sleep came faster easier slept about 5.5-6 hours.

3rd night fell asleep around 3 am sept till 8:45 am woke up realized I slept, stayed awake for 2 hours then fell asleep again for 1 and half hour.

Night 4 took 2 hours to sleep, so 4 am, woke up at 10 am due to dentist appointment

Day 5 fell asleep fairly easily ish, slept up until 11 am woke up briefly, dreaming was really vivid to

Is it safe to assume im past withwhy is it going this good? Will I have lighter nights,

Even if I can’t sleep for hours I will not take quetiapine again but yeah I just keep telling myself eventually I’ll fall asleep since that’s what the body does.
