Hi and Welcome....
I am not sure why you are doing the miralax before the prep. Are you constant constipation? I am mostly D so I can not advise on that. Usually the cleaner you are, the better it is for a scope so that makes it an OK idea. However, you want to make sure you don't dehydrate yourself.
Call and ask your GI if you think it is a concern about getting "clean" enough for the scope.
