Proobably about 12 to 16 hours I do beleive. Or basically the next day if you ask me.

There is a sticky here on the top under "home detox" that has an example of all of this and the example is withdrawing from vicadin. May be helpful.

I was addicted to vicadin and to get off of it, I switched to tramadol and now am addicted to that. It is less expensive but still sucks. I think the withdrawl symptons are a lot worse though on vicadin
