Yes! I have! So good to hear you say that because that was one of the side-effects I told my neuro about (pretty unhappy with heaps of things ie. Memory problems, weight gain, nausea, drowsiness, still having seizures at same rate anyways, maybe thinking about getting pregnant etc, etc, etc) and he just dismissed it all and pretty much just read the 'side-effects' listed on the side of the box, then told me more or less that I was imagining everything.
I frighten very easily and sometimes think I see things even when I know they're not there. My heart races if I walk out to the car in the dark at night. I never used to be like that and i'm positive it's the medication.
