It got better for me.

I also had a period when my moods would seem better in one part of the day than the other. It was the opposite time of the day than you describe. I'd feel HORRIBLE in the morning, and then even sometimes feel hypomanic in the afternoon. I suppose it was the right medication mix that eventually helped with that, for me. Though I do still sometimes feel very tired in the morning, it's not nearly as bad as it used to be. And even being tired, I don't feel unwell mood-wise anymore. Just a little angry at the alarm clock. Once I get going nowadays I feel good quickly.
