I had that revelation half an hour. I am not talking about something like what happens to some people who take Ambien and then have no recollection of their actions the following day. In fact, I only rarely take Ambien. But I just discovered that I do things when I have insomnia and completely forget about it the following day. And it's not just anything. Apparently, I am capable of weird stuff while I have insomnia.
I had insomnia last night. No big deal, since I didn't have to wake up at any particular time today. I hadn't gone drinking either. I just read, surf the internet, read some more until I finally felt asleep around 5am. I checked my work email for the first time today half an hour ago. And what do I find? An email from the university communications office (or something like that) with a $34 receipt confirming that I had ordered...BUSINESS CARDS!!!! Even better, the time on the email was around 2am. I thought it was some kind of spam because: a) I don't remember doing it and b) I've been at my current institution for 5 years and I've never got around to order business cards. To confirm, I checked my online bank statement and sure enough, there was a pending charge for $34 from early this morning.
So it looks like that at 2 in the morning I finally realized how essential business cards are. It beats expensive impulse purchases, that's for sure. And then, I just forgot about it. So I will have business cards for the next academic year. And hopefully, I'll have to order new ones in a year, if I get tenure.
Have you ever bought weird stuff a night you couldn't sleep? I am not talking about being drunk and thinking that you could not live without that amazingly discounted $400 Prada purse (I did that once and promptly returned it). What I have in mind are night purchases done sober, but that the following morning you don't understand why they seemed rational the night before.
