After a particulay large and dangerous fire (im a full time firefighter) i was "high" for a few weeks afterward. This was 5 years ago, but i can remember it like yesterday. I was in control for the most part, but i was definetly manic. I spent like crazy, had sex like crazy, well, i was just crazy.
But yea, a serious life or death situation will get certain chemicals poping in the old brain. In your case you are manic, loving life, enjoying it to the fullest. If you arnt in any distress, enjoy this feeling for as long as it lasts.
SOmetimes there is a good side to being BP, and this kind of euphoria is one of the perks. Think legal high. LOL LOL LOL LOL
