Thanks so much for writting me. Brittany has also been on Miralax, I felt like it didnt work real well like the Lactulose does. The reason behind this is because Brittany doesnt drink very much and when you mix the miralax in with liquids well she doesnt finish it. But the lactulose is different you take a TBLS and only need to drink a little with it. By the way the nurse called and their was no abnormalties in the ultrasound yesterday. Now they are planning to do lab work. Thanks again.
