Well no one responded to my post yet and in the mean time my husband is a bit better, so I'm going to answer my own post in case someone in the future needs the answer.
If you wean fairly quickly off of Lamictal XR you may have "feeling like you are wired" insomia for about a month, then it will start to dissapate. I will add however that my husband has been having neurofeedback treatments twice weekly for the past few weeks (never did it before) and he has not had any seizures (which was likely coming off of the Lamictal XR and not replacing it with another seizure med) and it may have helped with the insomnia. If any one wants to know how the neurofeed back works out-- respond to this post.
Hope this helps someone!
