Not that I'm Superman or anything, but...
I truly believe that throat/sinus infections are my Kryptonite. Today marks one month to the day that I have had this crap in my system. Fortunately I've been quite functional for most of that time, but I'm only now starting to hear my voice return to normal as the last of the brain goop seems to be leaving me. I feel so drained, just a deep kind of tired, when I catch them and I think, in a way, that this only exacerbates the problem. I don't always recognize this, but tonight I did and I forced myself to get on the hamster wheel. Exercise always makes me feel better. Especially when I can breathe while I'm doing it. :)
