Hi, so yesterday I started my pre- op liquid diet. Surgery is on Nov. 12.

well, I’ve had a massive headache since yesterday. I don’t drink sugary drinks so I know that isn’t what is causing my headache. Anyone else suffer from headaches during preop liquid stage?

Do you normally drink coffee and have stopped now? The withdrawal from caffeine can be horrid. Also cutting out carbohydrates can also do it as well. I dont think it's uncommon to react that way. Try drinking more water. Headaches are a common side affect of being dehydrated.

Agreed...I had it in spades when I went on my pre-op diet along with massive amounts of gas.
