Is this ADD? Or menopause?

I've got the attention span of a toddler. I only half listen to phone calls anymore and even after the rare one in which I'm fully engaged I forget details within a matter of weeks. I use the DVR a lot, and thank God they exist because I have to re-watch things at least twice before I finally grasp what the hell is going on anymore. I want to speed-read books like I used to, but if I try then I can't tell you what the hell the book was about. I don't seem to need 8 to 9 hours of sleep anymore. Five or six is about it. No matter how cool the house is, I'm overheating in the wee hours of the night. Not "drenching the sheets" hot, but hot enough to wake myself up. I lose crap all the time and it's damned annoying. Every time I clean up and organize a space, I can never remember where I put something when it apparently made perfect sense to me at the time I was straightening up. And I'm already bored with this topic.
