Thanks for the info! After searching online, it really is a side effect that is experienced by a good number of people. I am wondering if the Lamictal was increased too quickly... our neuro doubled the nightly dose ahead of schedule due to a seizure in which we had to give our son Diastat. I agree and think pulling back on the dosage makes more sense than increasing it if we don't get some relief with these tremors some time very soon. When we have upped meds in the past in reaction to an especially bad seizure the outcome has not been great to say the least. Really hate making a guinea pig out of my kid... UGH!
