I'm finally going in for my first colonoscopy after 5 years of possibly having chrons. I'm super nervous, and have been given the magnesium citrate prep. I finished the first one, no probelm, down in less than an hour. But I can't finish the second one and I'm nervous that I won;t be... 'ready.' I am still going to take the 2 ducolex (sp?) tablets tonight, should this be enough? I ate light for the previous day and I am very nervous, if any one could help? Thanks
