bluebicycle, I definitely know what the double vision is all about. I experienced it off and on with my Tegretol XR (carbamazepine ER). Often in the beginning. Do be careful. Can someone take you home or pick you up if it persists? I agree that you should talk to your doctor about it. I recently had my Tegretol XR decreased from 1400 mg to 1200 mg and it made a difference. I had been taking 1400 mg for several years. Things change.

I hope your back recovers soon and your stomach feels better.

I'm very sensitive to changes in my medication taking times, too. I'm a 7 am and 7 pm med taking person. Breakfast and dinner on the dot.
