Well, it's 4 AM here in MS! I do the same thing you do. I won't sleep or sleep very little for several days, then I crash. I don't have a hubby to miss, though. I actually just got invigorated about 10 pm tonight and did a few chores, "decided" what I might want to work on tomorrow (today??) and made a list. I'm very good at lists! LOL I was kinda busy off and on today but around 5 pm, I hit a "crash" and had to lie down. I napped until 10 pm...which is one reason I'm up now but I've found that I have to take sleep as it comes. :(
