I think that he was telling you that because some do have a significant amount of calcium in them. Tums for example is also used as a calcium supplement and certain kinds of calcium will constipate you. Make sure you get the pharmacist to tell you exactly which one to pick if he didn't already. Sometimes the labels aren't clear enough to determine that since many ingredients have different names for the same things.
Did you start the Miralax? I think that should help you because it will draw more water into your colon to hopefully ease the stool out. Much luck to you and I hope you can find some relief from the C and indigestion.
