I am on my pre-op 1 week liquid diet and my head is killing me.

Another poster just posted the same thing. Are you a coffee or soda drinker? Are you avoiding them now? Perhaps caffeine withdrawal?

I do seem to remember having a headache at first too. The body is starting to burn the fat it stored away and all the other crap that goes along with it. Body fat is NOT a clean burning hi test fuel and tends to really make you feel crappy while it's burning it. In fact it's call KETOSIS. You're kind of early in the process to start ketosis but it MAY be an issue.

I have avoided ibuprofen this week (my surgery is monday) just because I want my stomach as easy as possible before surgery. And of course, that TOM is upon me. I have taken a tension headache pill which is acetamenophine and caffeine. Hasnt worked for cramps but got rid of my withdrawal headache.

My surgeon told me not to take any ibuprofen a month before my surgery and I stopped prolly three months before that.
