Sorry to hear that Rundogrun.
I've actually switched back from morning to night, as after being at 10mg for a while. It seemed more sedating during the day.
As for how I sleep at night... it varies. Sometimes well and others not but there are other factors like me using nicotine patches during the day & the fact I never slept perfectly before starting Abilify anyway. My best guess is it really isn't affecting my sleep that much one way or the other apart from making me go to bed earlier.
