Thank you for your interesting comments Hurdity. I dont want to sound flippant but.... I am sure my urine infections will not clear up by my diet alone ... I wish. My daughter has a bad chest infection and definitely needed a course of anti- biotics. Her diet is excellent! I cannot tolerate alot of the foods you listed eg tomatoes, turnips, and gooseberries. Maybe thats why i had a reaction to the D mannose. Not yet tried it again, as a bit nervous and i know i need a day when i am at home all day. x
