I have blacked out and it was only on these crazy pills that I got from this German guy when I was in Germany..he said they were caffiene and to take 1 and drink some coffee and you would feel good...well, I took 2 cause I thought he was a pussy...and the last thing I remember was saying to myself "I think I am feeling something". Shit, I woke up 8 hours later in a baunhof (train station) with people stepping over me...I missed formation that morning..but I didn't get in trouble..I will never know what the pills were...but I do know that was some strong ass shit. HAHA! I lived!
