thanks for the info apathy24, but i forgot to mention the guy at my local head shop made sure to tell me not to drink more water than 16 ounces, which is the size of the xxtra clean bottle. This is what the taped instructions say:
Start: 1 hr 30 min b4 appt. on empty stomach drink bottle wait 15 mins refill with water, drink bottle wait 1 hr, go to bathroom while you wait at least 3 times, done, clean for next 5 hrs. then he went on to say NOT to drink more water than the refilled bottle or i will dilute it.

Followed the instructions for the exception of that damn coffee (which now I'm hoping was the reason why i failed). again, any help would be greatly appreciated.
