All the time. It is scary, annoying, embarrassing, I can think of a lot of words that come to mind when it happens. Especially when I am talking to somebody and feel like I am zapped out of my train of thought.

Hi,
i know what you are both saying. When I was taken off my normal fast release tegretol and put onto tergetol cr the slow release including the epilim I would get these weird sensations. Like statick electricity in my head on a particular spot. I would have to stop what I was doing it would feel like I was breathing from the outside in and that my heart and everything was going backwards. My vision was the worst. I would be on the telephone taking down a note and all a sudden I would phasein and out with my sight. From left to right it also felt like I was looking inside a tunnel and that I couldnt see what was going on either side of me then it was scarey the first time, because you are aware of it all then it would get more violent and make you feel like your eyes were shaking from side to side in your head but your eyes wernt rolled backwards. Still keeping in mind the statick feeling in the head and down the neck a little. It was kinda like I had frozen and what seemed like forever was only like 10 seconds but it would always happen when I was writing and now it is still hard for me to focus on a small object. Like being cross eyed.
Well thats how it felt for me.

Yeah, it happens to me too. But the only way I can explain it is a static rippleing feeling in my head. And if I close my eyes I see jagged lines.
And sometimes I get a killer headache afterwards.
