I have what seems to be a basic question, but I can't find anything on the net about it. If one is a regular, but non-daily user of Vicodin, how long a "rest period" should one take so as to get the best experience? I find that when I've been without, the first and maybe second time are cool, but then not so much afterwards. Will a few days off be enough? A week (other)? Thanks for any help!
