Do some experimenting with diapers, and find the one that suits you the best. Then, anytime you know you are going out drinking, put a diaper on first. If you use it during the evening, change it before going to bed. If you think it may leak, use a bed pad, too, or sleep on a towel like you first said. There's something else going on between you and your girl friend concerning your incontinence. I suggest you get to the bottom of the problem, and determine whether your friend or your drinking are more important to you. One doesn't need to drink alcohol in order to have fun or enjoy onesself during the evenings.
