If you feel that something in your diet is hampering your attempts to manage your urge incontinence, but you don't know what it is, try keeping a bladder diary. This is a daily record of what and when you eat and drink, and your urination patterns. You can also try an elimination diet. Remove one item -- tomatoes, for example -- from your meals for a week. If your symptoms get better, note that. Gradually add back small amounts of that food and see if your symptoms come back. You may be able to have some of the food without the irritating side effects.
