I take 150mg. I was stepping up the med and hit 150mg and my Pdoc and I decided to just "sit there" for a while.. I think it just took time for my body to adjust to it, well any med to be honest. I do also take Lithium but it was my second try on lithium that worked, first time I was too impatient for results lol
I'm sorry I can't remember if you had tried it or not.

I hope you find something soon that gives you some relief.
