Our bag of Ketamine(about 5-10g) fell into my friend's cup of coffee, and we decided to drink it anyways,
so we really stirred it in, and I'm not entirely sure how many sip I took, but it was more than enough.
My vision was blurred and scattered to fuck, I was face-down on a mattress, and the floor under the mattress looked like the fucking infinite abyss that was going to eat me up sooner or later. I was unable to move or speak, it lasted for fucking hours while I was staring into the distorted face of Hades, I felt like I was going to vomit any second the entire time.
In short, it sucked. Ketamine sucks, never touched that shit again.
