7rider,

I had a doctor tell me one time to skip the yogurt and simply purchase acidiphilus tablets. He/she indicated the tablets were more effective and efficient in reculturing ones gut. I have had great success with the tablets and now take them year round. I was told I did not need to separate them from the antibiotics but must keep them in the fridge. Not sure if this is helpful but I hope you find something that works for I feel your pain/discomfort.
