I am on 350 mgs of quetiapine and i still have problems getting to sleep. My meds are adjusted to prevent this but it still takes forever to get to sleep eventually if and when they kick in. If I am woken from my sleep, it takes forever to get back to sleep.I take 200 mgs, time release plus 6 25 mgs that are supposed to lull me towards sleep. I have been on the same dose for 10 years.I am also on lithium, lamotrigine for epilepsy and clonazepam. I steer clear of caffiene at night. Exept for a cup of tea to help my meds kick in faster. Why is this happening and what can i do to get my sleep pattern back. This has only been happening in the past week.
