Anyone have experience with seroquel?

So I had an appointment with my psychiatrist today. I was hoping to lower my abilify from 10mg down to 5 because I have no motivation or will to do anything. But instead we upped Wellbutrin from 150mg to 300mg and added 50mg of seroquel for sleep as needed. Anyone have experience with seroquel? Can you tell me about it. My psychiatrist mentioned if I like seroquel and do well on it we could swap it out from abilify
