Good Morning
I have not used Seroquel but I do use Trazadone for sleep. You are on Lexapro and Klonopin which is a good combo but as someone so nicely mentioned each person reacts differently to the meds.
I hope you do well on your present combo. If you decide to try the Seroquel, ask your physician to explain in detail the purpose of and expected outcome of choosing this med.
Gentle Hugs
