Probably, although that was at its worst. The recovery was a continuum spread over a couple years, so there were pretty long periods of mild impairment as well.

I think you're probably right about happiness, but I didn't find that my impairment helped me relate to others. Even when well, I feel like I relate to most people in an 'emulation mode': a feedback loop of consciously gauging reactions and continually asking myself how my audience expects me to react. Being impaired just made this less effective and more stressful.

The general feeling was similar to being sleep deprived and unable to focus. Small concepts felt very complicated and hard to grasp, but at the same time I constantly realized that I wasn't operating very well. I suppose if the effect was more like alcohol, where the impairment is more obvious to the audience than to the drinker, that there might be more of a pro-social effect. I'm not much of a fan of alcohol, though, so again this might be just a personality issue.
