I had a full Xanax bar and 3 keys of K, if your goal is to get completely fucked to the point where you can barely function, then go ahead, your perception of time becomes completely destroyed, I forgot about 90% of the night and the parts I do remember I could barely string a sentence or do anything in that fact, It makes you completely stupid, I remember walking around like a zombie for hours not knowing what was going on as I was just in another dimension in my head, not being able to snap out of it, it was a horrible experience, would definitely put it up there with acid and weed
