I seem to be always ill. One bug after another. I am really really really tired, even though I generally sleep well, am woken in the night only once or twice per week. My diet is good. I get a reasonable amount of exercise, etc etc.
I might be a bit low on iron, and might try taking some iron pills or something (Not really eating red meat these days, and I get nosebleeds, so do need iron). But I'm worried it's my thyroid, particularly given how cold I am all the time.
