I havent experienced fogginess (beyond normal weariness or tiredness one gets at the end of a long day although it is alittle different?, but not worse)...hard to explain. It goes away immediately with mental effort especially talking to people, and is instantly dissolved by exercise. Green tea and coffee are also helpful for me. I was very worried about this side effect and had long conversations about it with my personal physician before starting. She said, " Dont worry, it probably wont happen." We decided if does and it becomes too bothersome, that I cut back or increase more slowly. (or change strategies)

I have a profession where I communicate delicate information and make alot of decisions. (I am a health care professional in private practice) I have to read and write complex information as well as speak and think it. The times I have found myself spaced out have been when I have gone too long without eating. So watch out for that!!!

Best of luck
