I did the pills...ohhhhhh..I thought "it'll be so much easier than drinking all that stuff"..noooooooo!!.. consumed the 1st round of pills (you take so many and then wait a few hours if I remember right..) and nothing .. then started the 2nd round.. cramping soo extreme.. and then finally "it started".. the pills are very large.. so the last time I drank the stuff.. and you know.. they said I could have chicken broth.. funny thing.. the stuff tasted better than the chicken broth...I had to do a "2 day prep" and ended up not eating anything solid for almost 3 days..if they tell me pils again..I will run!! And I'm usually very complacent...and cooperative.. the doctors just say 'you're so nice.." not always !! No more big pill prep..no more nice little old lady if they try!!
