OOOh ick, that is a drug you shouldn't do that with, there isn't any flexibility with that drug at all, it's not like lithium where you can up it a bit. Was this purposeful? are you sure it was just a double dose, if it's more go to your local ER, it could make you seriously ill. I would suggest if it's just a double dose, it will pass, I did that on celexa once and I was green around the gills. I'm forgetful.
