i got of lithium after too many side effects and being on it for 35+ yrs. never helped with my insomnia and racing thoughts. i love taking 1/2 seroquel knowing i will not ever have racing thoughts and my sleep is deep and yes, the dreams are vivid, ongoing it seems even when i get back into bed after peeing, and still with me when i wake up…and even tho i'm groggy for about 30 min. every morning, it helps slow down my mania and i'm not on any other mood stabilizer now.
