Sorry to hear about your hospital visit on Christmas Eve, bless your heart!
Luckily the rash that I got last week was not an effect of the medication. It looked similar, but it seemed to be from an allergy to a cat of all things and has cleared completely up.
The rash started out on the front of my legs (I belive around my knees) and spread from there, and also on the back of my legs. It started out like really bad mosquito bites. It started spreading, mainly just straight up and down. They were like a cluster of little tiny bumps that were extremely red. The doctor took me off of the Lamictal and they started to go away but it took a few weeks to get completely rid of it.
I too was originally on Dilantin and felt like a zombie all the time. By the time I went on the Lamictal, I had tried to so many different drugs and this one was wonderful because I felt alive again. After I got off, he tried a few more, the side effects were always bad. He put me slowly back on Lamictal about 6 months later and I didn't get the rash that time, not sure how often that can happen??
Anyway, I hope that I helped you a little!
