Every so often I experience a persistent state of euphoric excitement, usually in the morning for a few hours. I\'m experiencing it now, in fact. This is likely to be a combination of numerous psychological and physiological factors--really wonderful dinner with Cat last night, managed to get just the right amount of sleep, had a large iced coffee this morning, &c..
At any rate, it feels like I\'m vibrating exultantly. It is a pleasant sensation.
