trazodone knocks me out in 15min if i take it on an empty stomach.
olanzapine made me gain 15kg. my psych said you can gain up to 2kg/week. he, himself, used olanzapine and gained 20kg in 2 months.
but it's a great crisis med. never heard about it being used to insomnia, great to know!
also, quetiapine is another knock out but it also gives a lot of hunger, and you wake up dizzy, basically dizzy all day long. i took 50mg and 25mg and it was basically the same effect.
