Gee, I don't think it is the meds., but I am not a doc., but I have been on Lamictal almost 3yrs now (200mgs per day)
And it agrees with me. I do only take that, so it may account for me not having any side effects, if there has been I haven't really notice any, or remember what it was like when I was titrated to this dosage. I did feel agitated and wound up when I had tried 225mg per day, so 200mg seemed to be the target.
I suggest you contact the prescribing physician and tell him or her what is happening to you, you may need a dosage adjustment and or need to switch to a different med.
It is also important to find out if this is being caused by the Lamictal or some physical problem, I would contact them ASAP if I were you.
I hope all works out for you, please take care now.
