No Food Headache

I swam farther than I ever have. Do I then reward my body for
the work? No. I starve it. I want to lose some weight...
drop the belly so I didn't eat after the swim. I woke up in
the middle of the night shaking. By morning I had a hideous
headache. Not cool. I took 1000mg ibuprofen when I woke up.
That was a little over an hour ago but my head is still
hurting. Have a number of meetings this AM.

Update: It's 10:46AM. Just had to take another 1000mg of
ibuprofen. Have eaten two bagels and a breakfast bar. Still
hurting. Not massive pain but hard to think straight.
