I have tried many incontinence products but they all leak and smell after a while. What should I do?

You don't say anything to suggest any particular answer, so I have to guess. I guess you have a magnesium deficiency. That is very common in USA. Magnesium strengthens muscles, calms nerves, stops cramps, and fights infections. Get epsom salt. It is cheap, five bux for a year's supply. Put a dose in a glass with water to cover and stir until it dissolves. Fill the glass with lemonade and drink it. You can take it without the lemonade but you won't like the taste. Milk of magnesia is more expensive but nicer tasting and gentler laxative action. Your choice.
