Lemon juice is good, I always make a parsley tea with lemon juice and sip a cup morning and evening when I have kidney or bladder infection Work wonders, got the parsley tip from Margeret Roberts, she written about parsley in more than one of her books and it really works.
Good for all the "womens" complaints too! I avoid too much apple cider just use it when I have no lemon, I lose weight when I drink it and that's not a good idea for me lol
I love my Cider Vinegar drink...I make it with Honey...I do get weird looks when people realize what I am drinking.
