I have been taking Seroquel for insomnia for almost 9 years. my doses have been from 100mg-400mg. the problem is I wake up groggy even tho I only take one 100mg tablet now. sometimes I will sleep the entire next day until 4pm or 5pm. I know my iron levels are low. but still, I also know it's the Seroquel. I'm going to see my dr next week to see if I can switch to a sleeping pill. what sleeping pills don't make you lethargic the next day? thanks :)
