Why in hell am I feeling so good?

I can't figure it out but I've had a rush of feelin'-good energy overcoming me today. I mean, I'm almost giddy. Very unlike me ha ha. Reminds me of younger days when I could be giddy without reason for days, helped considerably by liquor, but this is a different animal. Maybe I'm getting ready to dive into happy Alzheimer's or something. Saw a patient on TV and all they did was smile and crack jokes. I mean, there are worse ways to lose your mind.
