Headaches with the liquid diet

I started a liquid diet yesterday and ended the day with a horrible migraine.  Has anyone else experienced this (getting a headache while doing the liquid diet)?  If anyone did get headaches were you able to find eating something in particular would help to get rid of them/prevent them from happening?

This is what I 'ate' yesterday:

2x high protein shakes (in the can)
1x slim fast meal-on-the-go shake
1x Strawberry Banana nonfat protein smoothie from Starbucks
1x can of cream of mushroom soup (98% fat free)
1x low calorie Gatorade
30 oz. of water with Crystal Lite
70 oz. or more of regular water (unflavored)

Then my head started to hurt soooo bad so I thought I have to have a quick sandwich for some carbs cuz' I figured my body was going through bad withdrawals of carbs which was giving me a headache.  So I made a cheese sandwich on lite whole wheat bread (2 slices) with 2 slices of 2% american cheese & light mayo.  I tried holding off all day (without eating any solid foods) but when my head hurt as bad as it did I thought I should try some carbs to see if it helped.

Should I be doing something different?  I'm thinking of running to the store today to get ingredients to make more smoothies at home (with protein scoops added) and also picking up more broth based soups.  I'm just worried about the headaches and wondering if I should add more carbs somehow??

If anyone has any tips or ideas I sure would appreciate it!!

Thanks! 

I was banded 11/02 and yes I had headaches the first few days.  Just make sure you are getting your protein in and your water so you don't dehydrate.  It will pass.  Thank God there is life after clear liquids!!!!

oh yes I remember those headaches, they were torture.  8 days fasting before my surgery and that was the hardest part of this whole process.  Nothing seemed to help my headaches but I guess they did get better after like the 4th day or so.  Good luck

I cannot take aspartame because it causes headaches.  I specifically got all my protein drinks without aspartame.  Today is day 4 and I have had a screaming headache for last 3 days.  I do think aspartame can be a problem for some, but I think that just going to high protein from high carbs is a problem unto it self.  Thank God it is only for a short time

 

What causes headaches on the liquid diet.  I was good until day 3.  I am now thinking it was the aspartame in the Crystal Light.
