It knocks me out. If I don't take it I have insomnia, because I'm so used to the drugged sleep. I'm very groggy when I wake up in the morning, and a little tired throughout the morning. In the evening I feel good.

I had to switch from the regular Seroquel to the XR because the regular stuff gave me an extremely rapid pulse about an hour after I took it. I wonder how that can be, because it makes me so sleepy and inebriated. I'm thinking maybe it slowed me down in my sleep so much that I stopped breathing, then woke up and the rapid pulse was my body trying to get oxygen (sleep apnea, I guess it would be) . I'm only thinking that because the rapid pulse was always upon awakening in the middle of the night. I haven't had that problem on the XR-it knocks me out all night.

I'm on 200 mg. I was on 300 but reduced it because I was sick of being so tired all the time and sleeping through every weekend. The fatigue with the 200s is more manageable, and my mood is still pretty stable.

I don't have a problem with loss of concentration or being spaced out on Seroquel. I had that problem on Abilify.
