i have the answer lol

yes u can take 600 mg or more of seroquil and still function

becuase u wont get prescribed 600mg from the start

it will slowly be increased to 600 and your body will adjust to it

u wont even be sedated in the end

i was on 700mg of thorazine and felt compltely normal

your body adjust to it , it sounds like alot but u get used to the feeling and u might feel sedated at first but the sedation feeling will fade away in time
