Thanks so much for your reply. I have an appt with my neurologist next week and so I can ask him. I will research the website for Vicodin and see what I can learn and check with the pharmacist. I don't take any vicodin after 7:00 PM and so it's a good 12 hours before my next dose. I will experiment anyway because I have enough in each day where I don't go over and actually always have extra.
Have a good day and thanks again!
