Hi, @num1boxer1919 - welcome to Mayo Clinic Connect. I can imagine you would be very uncomfortable with the heart racing from the quetiapine (Seroquel), and it's understandable you are looking for an alternative.

If you click on VIEW & REPLY in your email notification, you will see the whole discussion and can join in, meet, and participate with other members talking about their experiences.

I'd invite @flpatt @anniegk @yangedd @highserotonin30 @mxyzptlk @tness360 to return and speak to their experiences with quetiapine (Seroquel) and any heart racing they may have encountered, and share any thoughts they may have on alternatives for antipsychotics or insomnia.

I'd also suggest looking at this thread on insomnia in our Sleep Health group, which may have lots of ideas for you and would be a great place to interact with others who are trying to get better sleep https://connect.mayoclinic.org/discussion/josephene-i-am-having-terrible-insomnia-as-well-nothing-seems-to-help.

Have you had the chance to ask the prescribing doctor for the quetiapine (Seroquel) for an alternative, or some means to deal with the heart-racing side effect, @num1boxer1919? Are you getting much sleep right now?
