Oh yeah, Lamictal and blurry vision totally a side effect. I take 200mg in the a.m and 300mg at bed. I can only reccomend you request the normal strengh one. Also, my ability to drive is almost impossible for at least 3 hours after a dose so I now take my Trileptal in the a.m and save the Lamictal for when I know I am safe at home or somewhere for some hours. The effects have never eased for me over time(sorry, just my own experience). The nausea occurs from the visual disturbance in my opinion. It also makes you feel awful doesnt it? But, it does help the BP so what can one do?
Good luck and tell the doctor.
