Cranky -- we've been having my thyroid checked every 3-4 months for about 10 years. Nothing.
We've had my blood checked for sugar problems or anemia. Occasionally, I'm anemic, but not often enough to be this tired all the time.
We've tried various medications, stopping them, switching to others in case it was something like my allergy meds. Nothing.
We've checked for infections. Sometimes that's the case and the antibiotic will help, but most of the time, nothing.
I am depressed (after losing my dad this year and some stuff going on at work), but I'm on meds for that and while I *am* able to focus on tasks again *finally*, it didn't help the energy levels that much.
I've tried sleeping longer at night. I've tried "catching up" on sleep on the weekend. I've tried getting *less* sleep. Doesn't matter whether I get 4 or 12 hours of sleep a night, I'm always tired. Anywhere from so tired I can barely stay awake to just groggy, but always tired.
I've tried drinking caffeine, that doesn't help too much. Tried cutting *back* on the caffeine. Did worse than I was doing *with* it.
Um... what am I missing....?
Basically, in an average month, I'd say I have maybe 5 days where I'm not anywhere from quite tired to barely making it through the day.
The only time I can say it's easier to get through the days is when I'm on vacation, and even then I'm tired -- it's just the adrenaline will push me through and give me a burst of energy.
Actually, there is one place where I've felt better than I have in years, and I still haven't figured out *what* made the difference. That was Switzerland. After I adjusted to the time zone, I wasn't even half as tired in Switzerland as I am here. I had more days that were better energy-wise. For once, I felt *normal*. I don't *think* that was just the change of scenery and adrenaline, though it may be.
Whatever the case, we're still trying to find out why I'm so tired all the time -- I just never have had the stamina of most of my friends. I did try exercising more and eating better and while those helped a little, it was 50/50 whether the exercise would give me more energy or just wipe me out even more.
One thing I *do* know... my mom suffered from almost the exact same problem when she was my age. Being tired a lot, no stamina, and no medical test could identify the problem. Finally, when she was in her 30's, thyroid problems showed up on her bloodwork. We're expecting something similar with me.
