Query: Thank God for this product!!

I began working in Afghanistan approximately one year ago. I was on the verge of returning home due to stomach problems. My doctor at home told me to take anti-biotics to kill whatever was in my stomach and to begin to take Primadophilus after I was through with the prescription. I had nothing to lose and I followed his advice--JACKPOT! I have had very little problems since and everyone in my compound is now using it and we are in pretty good shape!!!
