This is not my field of expertise, but could you still be adapting to more normal blood sugars?
that does sometimes trigger unwanted symptoms. Try a variety of painkillers. Ask the pharmacist and get generics NOT the MEGAbucks branded ones. Try a little gentle exercise, whatever you can do. keep a close watch on the BG. you need to aim to be down around 5. That's the non-diabetic level. You may not get there to start with, but keep at it. once everything settles, you may very well feel a lot better.
