Thanks everyone,

I think I will give the 400 mg a shot. It has a little more side effects compared to the 300 mg (mild occasional twitching), more sedation, a slight increase in appetite.....but these would only happen on occasion, unlike when I was on 600 mg, where the side effects were a lot more intense. My blood pressure would drop in the AM, unless I took it easy getting out of bed, and that was scary (rarely on 400 mg though).

I was getting scared of long-term effects, like tardive dyskinisia and the extrapyramidal symptoms. I should put more faith in my pdoc though, that 400 mg does not really put me at risk for long-term problems.

What I will do is try it for a week or two, and see if it is still tolerable. I can get by with mild side effects, but if it's too much to a point it's making things worse, I'll scale back and talk to my pdoc.
