I advise mix it with lots of lemon crystal light to make the taste tolorable with out it i could not get it down...and do not be surprised that half way finished if you start gaging and feel like vomiting that is the same with most people...and be close to the bathroom as well.... during the procedure they give a light sedative if you are like me i go to sleep so do not know about it until after wards..... good luck to you :)
