I just started taking Horizant (300 mg) along with Lamictal. My psychiatrist made Horizant sound like Christmas in a bottle but I have my doubts. How long have you been on 3,000 mg? That sounds like a lot. My doctor said if you take too much it won't be effective. According to her analysis, it's like taking too many vitamins and you'll just pee everything out.

That's just her observation.
