Alcohol

I got this one. Amphetamines. You need both dextroamphetamine and levoamphetamine, or else just cut to the chase and jump right to big papa Meth.

It's really easy, the longer you stay awake the less you remember and the less aware you are of pretty much anything other than whatever stupidly pointless thing you'd stuck focusing entirely for hours or days on end.

• Bad memories? Who am I? What?
• Depression? I'm thrilled to be turning two cardboard boxes into a makeshift beverage cooler using floss and shoestrings. I just have to do this one last part. I'll be done soon. Eat without me.
• Self- awareness? There is only the box and the box is good and the box must be completed and I'm doing it and I did it and look how cool this cooler made of cardboard is!

Seroquel. Granted, you can’t drive or do anything cause you’ll be passed out. But you won’t be self-aware!

Dunno about meds but I know a girl who can make me completely lose my mind :p

Ignorance is bliss

Booze. But no, don't.
