Carpal Tunnel from crocheting

I do it every time, I swear.  Remember the afghan I crocheted?  Well, that went really well and I loved making it. Loved it so much I decided to do another one for another christmas gift. But, this one I decided to make more like a typical granny afghan, with multiple colors per hexagon.  Now, the other one I did in a month.  A month!  I started this one the first of November, and its December 21st and it is still not done!!  Yes, I am on the homestretch, but dang, this one is taking forever.  Of course it doesn't help that I chose to do this one in black, and well, I can't see the yarn with my glasses on, but can't see the football game on TV without my glasses, so spent the whole game last night flipping glasses on and off. (And they lost, they really should not have lost, very dissappointing)  This morning my arm is just aching, and I have to go home tonight and finish this darn thig, and then spend a few hours picking all the dog hair off the darn thing.  Ah well, holiday stress...
