I think we're all finally ok! Yuta had a day to catch up on his sleep on Monday, and while I'm still a little tired, we're definitely on the mend.
My tiredness could be due to lack of caffeine. I'm trying to take advantage of being forced off of coffee for a few days. On Sunday and Monday I just couldn't stomach it, and I figured by Tuesday that if I'd already gone three days without, I'd try for another. Truth be told, I'm really missing the *idea* of it - I really enjoyed the taste and having a nice warm drink every morning. Unfortunately, since the weekend coffee just hasn't tasted good.
So, I think that I'm past the horrible caffeine headache stage, and I'm going to try to stick with decaf, except in cases of dire emergencies. I really think I was having way too much coffee (two cups brewed at home, usually followed up by an iced venti Americano from Starbucks).
