I've done lots of this OP. Many many drunk nights. Might advice for you is to not go out in the freezing cold alone when you're 'toxicated, but if you can get a friend or two to come with and share the experience it'll be better and safer.
Sometimes in winter me and a friend go all the way down to the river at night, middle of nowhere, strip down, and go for an icy plunge. It's super dangerous and we might die, but fuck it's something special.
Pic relates - river behind us. You can't tell but it's usually fairly rapid and whitewater in winter, and especially spring of course.
