"25mg for insomnia. i always used to fall asleep and have a sound sleep until 3 am. comes 3 am. i used to wake up and stay awake until 5 or 6 am. this compromised my day. my experience is to take seroquel before 1 am. i get 8 or 9 hours of sleep every night. if i wake up, i am sure to fall asleep right away. on the flip side, i believe i became addicted to seroquel to the point that if i even miss one night i don&#039;t sleep well. oh well it&#039;s a tradeoff i guess."
