I'm also suffering from a remarkable lack of energy and motivation, but I don't think it is my meds, but rather a deep depression. I say this because a few months ago I was in the same low energy state and hardly taking any meds. Now I'm regularly medicated on APs and AD and still have no energy, so the meds didn't help so far. My blood test also are fine.

You can try to go off meds slowly or change them and see if it improves. It's a tough way to live life...
