Sharon, awhile ago you mentioned a probiotic that you purchased from Cosco do you remember the name? I am now taking the VSL#3 but I noticed it is starting to bother me. It gives me but burn I don't know why. I don't even know if they sell that probiotic here in the US. In fact I didn't know that they had Cosco in the UK. I would like to see if that helps me the way it helps you. I hope you are feeling better Thanks Grace
