add a good probiotic(example acidophilus) to the mix also. it's the good bacteria that lives in the intestines. you meds will kill it all, the good and bad bacteria. if you take the good even while killing them off they will re-cover w/ the quickness and you will feel better sooner and be more protected from re-infection. get them from a good store, not walgreens and they need to be refrigerated if not entericly coated. good luck the pmenonua bugs sux!
