If anyone reading has progressed to the point where the youngest children in your home are now over age 2, I have a question for you. Will I ever feel rested again?
My sons have been sleeping through the night--for the most part--since they were about six months old. We have had occasional wake-ups due to illness or for unknown reasons, but I have been getting a full night's sleep on a fairly regular basis for the better part of six months. . . and yet I am still tired nearly every day. And oddly enough, I am often more tired on the days after I've had a full night (which I define as at least eight hours) of uninterrupted sleep.
MM and I have been alternating nights of "baby duty" since the boys were about 8 months old. (Prior to that time, I did ALL the night wakings with them. Yep. All of them, even after I went back to work full time and MM was home on FMLA leave.) So I am guaranteed a solid night of eight hours of sleep at least three nights a week.
I don't stay up late reading or watching television. I am careful to limit my use of media (computer, TV, iPhone) within an hour or so of bedtime. I don't exercise in the evenings, as that has always interfered with my sleep, and I consume no caffeine after 2:00 p.m. I try not to drink more than a little bit of water after 6:00 p.m. so I won't have to get up at night due to a full bladder. (I generally drink two liters of water during the workday, so doing this isn't too difficult for me.)
I have recently resumed exercising three mornings a week. Nothing strenuous, just a brisk walk with the dog or 20 minutes of yoga. (I am woefully out of shape, more out of shape than I have ever been, even at weights 25 lbs more than my current weight, but that's a sad topic for another post.)
Based on all this, I believe that I am probably getting sufficient sleep, so I can't understand why I feel tired all the time. I'm not anemic. I have had my thyroid levels checked recently, and they are normal. (In fact, I have had quite a bit of lab work done, and the only abnormality found was that I am vitamin D deficient, something for which I am currently taking supplements.)
It's true that my stress levels are quite high, probably unhealthily so, nearly all the time. But apart from that, I really don't see any reason for my feeling so tired all the time. My sons are pretty good sleepers in the main, and have been for some time, so it seems like I shouldn't be so tired.
