I am currently super constipated. I took the recommended dose of Milk of Magnesia yesterday at about 7pm and its been 14or15 hrs and it hasn't done anything. I usually take magnesium citrate and it does the trick so can i take that even though i took MOM less than 24hrs ago? I am miserable and need relief. I even drank 4bottles of water after the MOM hoping it would help speed things along. Any advice or answers will be super appreciated
