I agree with Paxiled. We know our selves better than anyone.
It sounds like you're doing really good with the taper. In my opinion it was one of the harder meds to taper off of because of the dizziness and brain zaps.
I would recommend you take Paxiled advise because he always gives great advice and he knows what he's talking about.
Please keep us up to date on how you're doing.
The taper is dependent on you, not someone else. Don't let a doctor or psychiatrist tie you to some set schedule. Do it as slowly as you need to. If things get rough, and don't expect them to, many people have an easy time of it, go back up on the last dose at which you felt fine and taper off more slowly. So, for example, if the dizziness is too much to handle or doesn't seem to be going away, try tapering off more slowly. And going down from 20 to 10 sounds too steep, though you've already done it. Go down by smaller increments with this drug. And if you ever get post partum again, it's a hormonal disorder and antidepressants don't treat hormonal disorders. Taking an antidepressant and getting into the problems of them might not be the best solution.
