Safe laxative: C difficile usually overgrows because an antibiotic kills off the more friendly bacteria. We've used milk of magnesia (magnesium hydroxide) for centuries but only saw C diff colitis with the heavy use of antibiotics. Constipation itself is dangerous. I'm sorry your illness gave you PTSD and I would encourage you to work with someone who can help you process these memories and recover your strength. Best wishes.
