@mhi and others on C diff.. I too got C Diff when given strong anti-biotics.. only lost about 10 pounds.. but probiotics prescribed OTC type.. worked for me .. now each time I get an anti-biotic they write in the probiotic to go with it ... It works for me.. and every week or so I have to refresh the probiotic as I cannot tolerate the yogurt ... except soy yogurt.. Ken
