The only time I ever really thought I was gonna die was when I did 8 wanga's off the top.
Caffiene has never caused too many problems with me. Although I think my body gave up sending warning signs to my brain years ago.
How long ago did you do this, because i have never found wanga's that were that effective...sure i turn into a fucking retard after 8...but all has always still been well with my world....about as well as can be with acid anyways...but i know there is the whole, they dont make acid as strong as they used to thing
caffeine is different though, i use to drink 5 red bulls before work all the time and it was fine...but these days i have one, or a coffee and i need to crap 3 times in the next two hours and my brain crashes pretty quickly as well
