This is an obvious suicide attempt if an individual is planning to consume 80 mg of Klonopin.
If you're having suicidal thoughts you need to seek professional/medical help before resorting to this.
If you're trying to consume all these to get high - That's just moronic.
So I'm going to assume with my first assumption.
There are many people who are suffering from severe depression and there are therapies and medicines to help.
But to answer your question:
80mg Klonopin (depressant)
40mg Vicodin (depressant)
1500 mg seroquil (depressant)
40 oz malt liquor (depressant)
Mixing all these MAY cause respiratory depression or
resulting you to become unconscious and choke on your own vomit which would result into asphyxia and death.
Please don't do this - You will be hurting your loved ones,
and possibly putting people at risk if you end up driving and hitting/crashing into an innocent person/driver.
If you need someone to talk to there are hotlines, mobile crisis , and even someone at the hospital/ER.
If ANYTHING send me a PM and tell me what's going on. I could help you if you need.
Much love to you.
