I started my pre-op diet on Monday and by Monday afternoon I started with the worst headache of my life and it has not quit. It mostly feels better when I lie down. In fact when I get up in the morning it throws me for a loop because there is no pain when I open my eyes but I sit up and feel a knife go through my head. It is blindingly painful. I am allergic to Advil and tylenol doesn't touch pain like this. I had a similar headache after an epidural one time and that was a spinal headache and treated with a blood patch. Does anyone know why I would be feeling like this? Is it the lack of caffeine? I snuck a starbucks via into my shake this afternoon but it isn't any better. Just my body adjusting? Will it go away? I really don't want to go to the doctor until next Friday when I get on the scale, ya know?

Your body is detoxing from caffeine, sugar, carbs...I was told by Day 3 it gets much better...hang in there...the pre op liquid diet is said to be the worst part...drink water and rest as much as possible...

My day 3 was the worst. I was tired, fuzzy headed and could not think. My doctor said it was from detox and it DOES get better. I'm on week 2 and doing well. I still get occasional headaches but I think it may just be allergies. Good luck!
