Are you taking large amounts of vitamin c or magnesium? Those can contribute to what you are describing. So can certain herbs. You need to think about what you are eating, and what supplements you are taking. Perhaps you might need to decrease the amounts of vitamin c and magnesium you are taking, or else spread these out over more doses so you don't take too much at a time. Perhaps the threelac or 5 lac are causing the problem? Did you have the problem before you started on these?
