Please suggest an alternative medicine for Lamictal.

Hello doctor,

I am a 61-year-old and was later diagnosed by a doctor with fibromyalgia. In the last three years during the nighttime, I suffered from aggressive involuntary movements while asleep. Those movements include kicking in the air and arching and bouncing my back and the whole body. At first, those aggressive movements started as a physical response to a dream where I was being attacked which happened once in a while, lately, it happens more and more often without any noticeable reason. As a result of the movements, I suffer from strong pain in my back and knees which lasts for a long period of time and restrict me to my house. I am also very depressed about my physical condition which projects to anything I do in my private life, family life, and job. I quit my last job a year ago due to my medical condition. Can you please advise on physical/neurological treatment that will improve my poor physical and emotional conditions? In addition, I am using Lamictal 200 mg which according to the medicine brochure might rarely cause involuntary limb movement. Therefore, I wish to replace it with equivalent medicine. Can you please advise on a possible replacement? I have already tried Seroxat, Depalept, Gabapentin, Lyrica, Teril, and Cymbalta which did not help.
