Anyone have hunger headaches prior to surgery?

My surgery is scheduled for October 6th.  If I don't eat, I get these obnoxious headaches and feel jittery.  My question is if anyone had this problem before surgery and if they still have it after they have had the surgery?  Thanks for any info you can give!

Absolutely - this was something I experienced all my life prior to surgery.   The nice thing is that after surgery, I don't experience that anymore.  :-) 

Hi Smf - double what Tracy said! I would get the headaches and major jitters if I did not eat. After surgery, not once so far :)

I get them daily! I am on the liquid pre-surgery diet now, and if I don't space my shakes out evenly I get them...
