Yesterday was quite tiring for me. My daughter had her annual check-up at the doctor's office. It went well, but there was a lot of running around afterward. Needless to say, I had to grab a little half hour nap in the afternoon. Sometimes I wonder why I get so tired. Do I need a pulse oximeter to check the oxygen level in my blood? I don't think that it's sleep deprivation. I tend to sleep a LOT when I can. I don't want to be tired all the time!
