I don’t drink any extra liquid, but I do drink a lot (probably too much!) tea during the day and quite a bit of water too. Occasionally I’ll have a beer, cider or a glass or two of wine in the evening.
Usually, if I wear a nappy to bed I will often wet slightly before I go to sleep, wake-up once needing a wee in the middle of the night and just wet myself and finally I wee in my nappy in the morning when I wake up.
I find if I have some kinds of fruit in the evening however, oranges and raspberries etc, they act as a diuretic and I can end up wetting frequently and my nappy, boxer briefs and plastic pants are soaked in the morning but fortunately the bed stays dry.
