I went no mail on pretty much all my email loops. I've got a ton of notes I need to answer; they're sitting in my inbox, making me feel guilty, but I doubt anyone is getting a reply until next week.
I'm trying to get 8 hours of sleep just because it keeps my brain sharper for writing, but if I could last longer without sleeping, I'd cut that down, too.
I do try to take breaks late in the afternoon. I've walked down to my garden and taken a half hour to just look at my flowers and enjoy them. It's not as much fun as it should be because I'm wearing a sweatshirt and a jacket and it's nearly June! But I'm doing it because I know I need the time away from the computer. Not the story, the laptop.
I know other writers who get like this, so I know I'm not alone. Maybe if I didn't have to take vacation from the Evil Day Job to work, it wouldn't be so intense when I do. Anyway, I won't be blogging on Friday because I'm on deadline. :-)
