I don't want to be "that" herbal hippie person, but I've used St. John's wort for ennui/mild depression. It seems to help me. Someone else said Vitamin D3 and I have to take that in big doses (my body doesn't store it for some weird reason) and if I don't I get slow and droopy. Hope you feel better soon!
Ugh, I have the opposite problem. Mine go on way to looooonnggg...
