I've only tried Risperdone, Latuda and Zyprexa. By far the Risperdone (combined with Zoloft) was the most zombiefying. The Latuda (combined with Zoloft) was just too expensive ($675.00) so I only used it for a month, not long enough to give it a fair shake. I'm taking Zyprexa now and combining it with Prozac and it has so far been the least sedating. I've been taking anti-psychotics for over 3 years now and you do get used to the side effects...that being said, I still take a nap just about every afternoon.
