I was put on it for post partum depression after having my twins, and that helped tremendously. At that point i didn't feel any side effects.
Recently i have decided to go back on it, after off for about 8-12 months, and now i am restless with minor headaches. I just don't know if that is me being a restless type person or the medication.
I do know that you have to give it that intial time to get use to it.
