Today is my 3rd day of eating low carbs.  Never done anything like this before
in my life.  I don' t need to lose a whole lot only about 15 lbs but my wife
would like to lose more so I'm doing this with her.  Ever since the first
night I've had a headache and it's gotta be caused by what I'm eating.  It's
almost to the point where I want to start eating what I was eating again.  
Here is what I've eaten in my first 3 days.

Day 1 - 3 eggs, 3 sausage links for lunch.  chicken fajitas with low carb
tortillas for supper.  Drank mostly water.

Day 2 - First day of work while doing this.  Was starving at work so snacked
on mixed nuts and drank diet Mt. Dew.  Lunch was leftover chicken fajitas and
water.  Supper we went out to a buffet and only ate meat.  Had steak, ham,
hamburger patty with cheese, ribs, and a chicken breast.  Drank  Dt. Pepsi.

Day 3 - Ate more nuts and drank Dt. Mt Dew at work.  For lunch had 2 LC Subway
wraps.  Tonight will prolly have some fish and not sure what else i'll make.

During the evenings while at home I am drinking water but I am guessing that
my headaches are from not enough water and I should be drinking more.  Any
other thoughts on what is causing this 3 day long headache?  I am very active
in sports and am in great shape already.
