Ahh, the wonderful world of Seroquel. I too get the "stupids" on my Seroquel....feel like a full-on drunk, stumbling about and knocking into things, you know what I'm talking about.
My pdoc told me if the full dosage was too much, it was totally cool to break it in half. But, I'm not a shrink, I just play one with my stuffed animals at tea time
At any rate, at least I'm referring my professional advice on to you.
Hugz and Much Love,
