Oh my GRACIOUS! Once I D/C'd my Tramadol before a surgery bc I didn't want to be too sedated. As you can imagine, I suffered a brutal textbook withdrawal! I waited days and then called a doctor friend and he explained it all to me and gave me some meds to help. This was for several days post-op. I've learned a lot over the years about opiates the hard way! Blessings, Sunny flower
