my son has been on it now for about 4 months and has tried to com...

I am sorry your son has suffered like this. It took me 7 months to successfully switch from Keppra to Lamictal - and it sucked! Each time I dropped a bit of Keppra I had a partial seizure. In turn, my doc kept cranking up my Lamictal dose to 600mg a day. I had a break through seizure about 4 months ago so now I am on 700mg a day.

Hi there! i had trouble sleeping a doctor diagnosed me with a sleeping disorder! i was then put on lamictal and 2 weeks later i got seriously depressed and i was having weird uncontrollable thoughts! my mind was racing too! this is definitely the lamictal. now im coming off the lamictal i dont have these terrible feelings.
for your son, please look into orthomolecular psychiatry( giving your body what it needs in order to heal itself) - going natural you're going to get the best results for your son instead of poisoning his body with all these prescription drugs!
take care, all the best
