Thank you for the replies
Last night about 10:30 it started working and continued until about 4am, so I was basically up all night. I am just relaxing today, drinking lots of clear liquid, and even though I hate Jello, I am forcing myself to eat some so that I can have something in my tummy. I have a history of not emptying properly, thus the fasting 3 days before. Today I have another two doses which I will start at 12 and 2 rather than later in the day. The Pico Salax isn't bad at all, I mix it in apple juice. My insurance doesn't cover it, it is $44 but working well.
Tomorrow is my test, I am scared but I will be sedated so I should be Ok. I am looking forward to some McDonalds afterwards, depending if I can stomache it....
Thank you again for the replies, this forum is great!
