I'm on day four of my pre-op diet, and also day four of horrible, morning-to-night headaches. I'm also incredible irritable and HUNGRY. My doctor doesn't do liquids - he has me on a low cal/low carb diet (less than 1,200 cals and 40 g carbs). He also has me down to one cup of coffee in the am with no caffeine starting on day 8. Is this caffeine withdrawal? Sugar withdrawal? Carb withdrawal? All of the above? I feel lousy and am having a hard time functioning at work and weekend holiday events. Please tell me this will pass.

All of the above. Try sipping on low calorie gatorade. Hang in there, you can do it. I had mine on November 23rd

On liquids too... The first day was awful. The headaches are nasty. My surgery is scheduled for Dec 27th. We can do this !!! Think about the big picture.

I had horrible migraines from morning to night on the first two days of liquid diet they passed as soon as my body adjusted it passed. Make sure your hydrated that's about all you can do

All of the above. Hang in there. It sucks. If you can, get a massage or go to the chiropractor or try hot showers or meditate or cold compresses on back of neck and forehead or icy hot on back of neck and shoulders. If it's really bad you can go to er and they can give a headache cocktail to break it. Just my thoughts.

Caffeine and carb withdrawal, also could be dehydration. I went through it too but I'm on day 5 of pre op diet of just plain veggies and Protein shakes and 1 cup of coffee when I'm used to two.

I had the same thing...googled and read about the "carb flu" which basically happens when you cut out carbs and sugar. It was miserable but finally passed after about a week. Hang in there!

Gosh you just brought back memories. Feels like a lifetime ago but I started my preop diet 5 months ago today. I had quit coffee a couple weeks before but also had terrible headaches on the preop diet but think mine only lasted a few days. Good luck! It will get better and be well worth it in the end!
