You might try going on zonegran, its considered the closest to lamictal.
And can be used in conjunction with lamictal. And then if it is working
for you. You can be slowly taken off or just reduced on the lamictal.
That is what we did with my son.
It helped to just even go down 50mgs on the lamictal for him. And
then when we found he wasn't even theraupeutic anymore. We weaned
him, but he used the lamictal for seizures. Not moods.
But zonegran is supposed to be the same thing as lamictal. But I am
only saying what I was told. With out the same side effects. One being
loss of memory.
