Aripiprazole is very safe even in very high dosages (lethargy/sedation, seizures, irritability, tremors, mild tachycardia). Fluoxitine is very similar (nausea, vomiting, rapid heartbeat, drowsiness, agitation, hallucinations, fainting, and seizures). The lethal dose of both is obscenely high. Also, taking a box of either, much less both will most likely cause you to quickly vomit leading to minimal dosages actually being absorbed by your body.
All this to say, please don't try to ctb using this method. You'll just make yourself sick and likely end up admitted to the hospital.
