Well, it's been an interesting road with this experiment.
First, I ended up in the hospital from medication toxicity. I guess the combination of the Trileptal, Lamictal and Ambien was too much. My doctor and I decided to reduce the Lamictal dose by quite a bit and cut my Ambien intake dramatically.
For me, the inability to sleep seems to have been directly related to the Lamictal dose. As I lowered the dose, I started sleeping better. I'm on 150 mg in the morning now and am sleeping like a baby with only 1/2 to 1 Ambien.
And the lower dose doesn't seem to be making me any more vulnerable to auras. I guess the Trileptal is holding me ok.
Finding the right med combination takes so much patience.
