Seroquel is an antipsychotic, but with a very sedative effect some people just don't like. A new antipsychotic, Abilify, works the same way, but with little to no drowsiness. I have been on Seroquel for almost 2 years, and lately had a lot of trouble with stability, in spite of my many other meds, so my pdoc added Abilify and viola! All stable now, and no tiredness. But then, I can't sleep without Seroquel so now I take both. Another member here, Anenace, started taking Abilify shortly before me and we both got REALLY straightened out, after about
2 weeks of not so pleasant side effects. You really should ask your doc if that may be an option.
