It gets unbearable. When I reduce the dose back to 600mg it gets bearable. But it is still there. I am wondering if anyone has had this reaction. It is my main med for pain, but it seems to be increasing it. I have verified this reaction by going back and forth between the 600mg and upping it to 1200+ then reducing it again. Any help would be appreciated.....
