There are a lot of good advice on here. My daughter has kidney stones too. They started when she was 16. Her doctor recommended the lemon water. He also recommmended no dark sodas unless you drink the equal amount of water after. Another friend said that his doctor recommmended apple cider. You are suppose to drink a glass and follow by equal amount of water. He said if you have an attack, don't eat and start this flush and it will relieve the pain. We haven't tried that but he said it worked for him. He also added that it has to be apple cider and not apple juice. Good luck with this very painful condition.
