Hi Rose, were you already tested for all the health conditions that can cause sleepiness?

Why not try a stimulant. I take a small dose now, and although they are not the greatest, it really helps with the depression. I, too, realized that I feel better when I am active; also productive and accomplish things. When I don't, the hopeless feeling returns--that my life will never get better. The stimulant helps you get going on projects, but it's properties also help me with mood in general.

If you want another idea, there is Agomelatine, the antidepressant drug that works on melatonin and resets your sleep cycle. Odd that you feel better at night but sleepy all the other time....

That sounds really rough. He is lucky to have you.
