I recently got bumped up to 400 mg (been on it quite awhile though) of lamotrigine and only at that point did it cause... yeah, "wobblies" is a good word for it-- as in grabbing walls and furniture while walking. (And vision problems, but that is another issue). Called psych after just a few days because other than that, like Skully's experience, it's been a really "easy" med for me, so I knew I had to call. Splitting it into am/pm doses worked like a charm.

You really are just getting started with it, so your body may well just be adjusting. Still, it's good to mention what's happening to your psych. (I had some small headaches and "hit by a truck" feelings when first starting, but they lasted such a very short time it's almost not worth mentioning...)

As far as hair loss? Nope. Sexual side effects? Nope. (Definitely had issues in that realm when misdiagnosed MDD and put on SSRIs alone, as in... zippo!
With lamotrigine though, no problem. )

And of course, welcome to the forums, NYBP!
