Jessica9190 127 Posted October 23, 2012 Thanks to everyone for your input. I didn't get to eat today until about 1:00 this afternoon and I had a horrible headache. I drank only Water today so I'm starting the caffeine take away Share this post Link to post Share on other sites
ecannizz 5 Posted October 23, 2012 I had horrible headaches after surgery for about 6 days. I thought it was dehydration but I was drinking non-stop. I figured out it had to be tension headaches- which can happen because of hunger. Don't worry, they go away, at least they did for me. Share this post Link to post Share on other sites
