Hi Lynn,
Ahhh the bathroom adventure! I, too, remember a couple of occasions where I was in so much pain that childbirth seemed like a walk in the park! What's worked for me, and I use this daily, is a glass of prune juice in the evening and also taking 3 doses of Benefiber each day. I've also used suppositories and MOM but the prune juice/Benefiber cocktail seems to work the best for me. Using milk of magnesuem sometimes would cause stomach cramps for me. Good luck!
Hugs, Nancy
