I have been taking 200 mg of lamictal for about 3 years. I am on no other medication. I too have the dry hacking cough that never ever goes away. All day and all night. Dry hacking cough that sometimes leads to gagging. It is terrible. I have had chest xrays, breathing tests and no one can find a reason for the cough. It started about the same time I started this medication and I believe it is the cause. I also experience pain in muscles, it's a roving pain that seems to show up in different places daily, sometimes muscle spasms. My stomach is always nauseated. Very little short term memory, runny nose all the time, constant feeling of having a cold, blurry vision, sensitive to light, little red bumps that appear on my skin, itch, then when they disappear, a scar is left like a cigarette burn. I am reducing the amount of lamictal I take as of this week. I am now only taking 175 mg and will for another week then go down to 150 mg. I am hoping some of these side effects will go away, if not I have to get off of it altogether. It's funny, because I didn't have all these side effects when I first started taking it. Seems the longer I take it the worse it gets. Just can't handle it anymore. wf
