Is it best to to take Rexulti in the morning or at bedtime?

My psychiatrist put me on 0.5-1 mg for depression.
I can't take it neither at morning, nor at night. If I take it at morning, it sedates me strongly. I can't work on it.
If I take it at night, I can't sleep normally. It makes my sleep shallow and interrupted. I am waking up exhausted.
I am stopping it for now.

I started taking Rexulti in conjunction with Celexa. I started with .5mg and have worked gradually to 3 mg. I was told to take it at bedtime, however I notice that since around the time I started rexulti I started waking up at 2 or 3 am. I continued taking it thinking it was unrelated .
About a week ago I started taking it in the morning and it's working out fine. I seem to have energy now through out the day and sleeping through the night. My only side affect is constipation.

Rexulti can be taken morning or evening, with or without food, but because it can cause some fatigue and sleepiness in some people it's probably best to take it at night until you know how it affects you.
