I started Neurontin at 300mg 3X /day. After only 2 days, I was totally looped. I felt as if *I* was outside my body witnessing what was going on. Of course, my doc was on a 2 week holiday so after consulting with another doctor went back to taking one 300mg pill at night without problems. When the doc returned, he recommended re-starting the 3x 300mg for a month. I had a slight easing of the fibro pain with that; the next step was 400mg 3X /day with more relief, but not enough.
Tonight I've just taken the first dose of 600mg, and am hoping that my body won't react badly to another dose at bedtime. If there is a noticeable improvement without crazy side effects in taking 3 doses of 600mg., I'll report back.
