In preparation for colonoscopy, I took one 10mg tablet of Reglan. Thirty minutes later, I began drinking Nulytely. I drank 1 glassful of Nulytely and felt I could not go on. I laid down on the floor and an hour after that, my arms and legs started shaking uncontrollably. I felt uncomfortable, sick, and couldn't do anything to feel better. The shakes lasted about an hour. About 5 hours later, I developed a migraine that lasted 12 hours. I then spent the next 2 days in bed with extreme weakness and tiredness.
