Would appreciate any words of encouragement regarding the above tests scheduled for July 5 & July 11. Am a big chicken & have been putting both off for years. Finally got some courage to see a gastro specialist & made appts for the two tests. I'm scared to death of the prep, feeling pain, etc. I have to take 4 dulcolax tablets & drink 2-3 liters of TriLyte. Thanks for your help. it is greatly appreciated.
