Fran - Lots and lots of water every day. Have as little dairy as you can, and avoid things like peanuts and chocolate. Supplement with a good strong dose of Vitamin C each day (either ascorbic or citric acid), as it creates an environment where the stone will dissolve before it's even big enough to cause a problem. All best.
