I'm on day 5 of my pre-op diet and lemme tell you, my head has never hurt so badly! I have tried everything I can think of to get it to stop but I wake up and go to sleep with the same one. I can barely see straight.

I figured there would be some detoxing, but since I don't drink soda or have caffeine I never imagined it would be this difficult - I was under the impression that was what most were detoxing from. I'm also starving 90% of the time but I expected that.

Please tell me this awful headache will go away?

The headache will definitely go away. You are detoxing from a few things not just soda. This too shall pass...hang in there! God luck!!!

I am on day 5 also. The first 2 morning I woke up with a headache. I drank a bottle of water and a protein shake and it got better.

You are essentially detoxing from carbs as well. The major change in your diet causes your body to have a temper tantrum. I quit my heavy diet coke habit a month ago because I didn't want to suffer through that as well as pre op detox. Thank god. I was miserable the first 4 days due to detox and the Protein shakes give me the runs. Today is the first one that I feel almost human. There's nothing to be done for the head. sleep, tylenol, lots of Water. That's all you can do and wait for it to be over.

Haven't tried protein shakes yet but been drinking tons of water! I'm up to go to the bathroom a million times a night!

Sugar has drug like actions on the brain, detoxing from sugar is worse than caffeine. And sugar is in everything.

It must be carb withdrawal. Looking forward to tomorrow and also my first weigh in.
