Ability is a very different beast some find it sedating others find it activating at the same dosage level, there has been a warning issued on it as well as federal action in the courts that it can cause a severe need to compulsively gamble , people have gambled away everything in there life including cars and homes , when it first was released they prescribed 30 to 45 MG a day , much like Haldol they have found in many cases less is more effective , so it's now generally 5 MG starting , and as with all atypical anti psychotics, have labs done before starting it and regularly well on it , or if any symptoms are worrisome , because all atypical can have an associated metabolic syndrome with them, this can lead to diabetes and other things , so carefull monitoring is in order .
