Anyone ever take Alinia?

I just completed my 2nd 14 day course and noticed that both times i was on the drug my Depression vanished and i was in very good spirits...i also felt mentally sharp & had energy. now, 3 days after i stopped, i feel kinda down in the dumps again. i have been pumping myself with high dose probiotics, but am wondering if Alina was killing something that was depressing moe or if the drug itself has anitdepressant activity. anyone have any experience w/ this?
