Lucylu from what I have read here you should take the yogurt as well. Kefir has different bacterial strains than yogurt so a combination of both on the diet is of course way better for the treatment.
Tell me about it. I ordered kefir grains online and first it was nightmarish to find anyone willing to ship here and when I did find a supplier, mine still haven’t arrived even after two weeks.
But I think it should be possible to get them in Ireland. Most sellers on e-bay and amazon are from the US.
