I saw that you are not using a diaper to help you with this condition. I think you should consider wearing a diaper to bed if you are going to have a cup before bedtime. It's better than waking up to a wet sheet and being miserable! An overnight disposable diaper would be preferred, or cloth diaper (2 for better protection, just in case!) and plastic pants. I hope this helps, hang in there! Cheers, Ian
