Oh my head!

I had great plans for myself this week in terms of exercise, but a three day migraine has all but ruined those plans.  I exercised my butt of (well not completely off, maybe a centimeter?) on Saturday, didn't get around to exercising on Sunday, and was going to do an aerobics DVD Monday morning.  Well, a migraine spoiled that on Monday, and then on Tuesday, and now today.  It's now 9pm on Wednesday night and my head is finally feeling okay, however I feel like if I make any sudden movements the pain is going to come back again.  Tomorrow is a new day and my plan is to do some low impact aerobics at some point in the day while my kids watch a movie.  I'm just nervous though because the aerobics on Saturday may have been what caused this mess in the first place.  It seems like I get headaches after I do any type of higher intensity working out i.e., aerobics or running, which is why I'm going to keep the impact low and pray that my head doesn't start pounding, or  fall off.  Hey, but doesn't the human head weigh like 20 pounds?  That could be an easy 20 pound loss...maybe I should jump around a lot! :-)
