I switched to Vicadin from the percs last night. No problem with it. but I only took 2 at bedtime. I have been taking the tramadol every 6 hours but seem to be able to cut that back to 7-10. I just took 1 Vic because I'm pretty sore to stand this evening, so we'll see. When I called for the refill she was willing to give me which ever one I wanted, percs or Vic. I opted to give the Vic a try to try and kick it down a notch. If they don't cut it she said I could call back for the other.
