Thanks to Kleiner. We do not use third-person aliases here OP. They don't really afford you any legal protection and besides, nobody is trying to prosecute us for simply talking about drugs. This is why we are so adamant about forbidding stuff like drug sales, drug synthesis etc. As long as we keep it scholarly, nobody gives a shit and everybody can be happy.
The conservative answer would be that you should not go to sleep. I know this is probably over now, but for those reading on, this combination of Heroin, Benzodiazepines and Alcohol is extremely dangerous. The synergy between the drugs is highly unpredictable. I'm not trying to be dramatic, but if I decide to write a book titled "How People Die From Drug Overdoses", I'm going to include this as my foreword.
