Thanks for the responses.

I'm on the same dose as Melissa, 200 mg twice a day. The dizziness has subsided, but now I am hypersomnic. I've been averaging 14.5 hrs of sleep the past few days (split up into 10-11 hrs at night plus a 3-5 hr nap). I'm not sure if this is reason to go off of it. In a way it's kind of nice, since I've been down the past few days and I welcome this lengthy escape from the world. Though I also think the oversleeping may be worsening the depression...
I'm seriously considering attempting to fight this illness with therapy alone. Meds have scary side-effects, and do they truly make much of a difference?
