I came across this site because I, and my family noticed issues when I was taking this pain medicine post surgically.
My behavior became somewhat erratic (while still "appearing" normal) I have had very large chunks of memory loss including conversations, purchases, and even disagreements. It's a scary thing to be able to come back and see something you've done (in writing no less) and have absolutely no memory of it.
I had a a complicated double hernia repair. So as a result they put me on this medicine as well as valium to control the muscle spasms. Im not sure if the reaction has occured because of the interaction perhaps? I've had to take valium a few times before and never had a reaction like this, to that medicine.
Im just curious to know if anyone else has had any issues like this.
