I had been on Depakote, a couple years ago, and then Lamictal, the Dep, may be the culprit here, check with your pdoc. again, like the saying goes meds affect everyone different.
So far, Lamictal has been my "friend", having no noticable side effects. . . but I must say my pdoc titrated up the Lamictal as directed.
Final words, check with the prescribing doc. about this, there can be a need for change in dosage, meds. or just patience as time allows for any "mild" side effects.
Just to be at some ease, talk with your pdoc.
This, is the best I can say.
Wishing you lots of luck with this, I understand (from experience) it can all be so frustrating. . . but please, do not give up.

Please take care,

DE
