I have a question about the laxative I need to take per my letter, it says to take 4 tablets of Dulcolax, 2 bottles of Citrate of Magnesium, I did all this except I am having a problem finishing the whole bottle of Citrate of Magnesium, what happens if I don*t finish the whole 2nd bottle? I have been going to the bathroom for the past 4 hours, thank you for your answer, do I have to finish the 2nd bottle?
