Headaches and Pickles

So it's day 2, and I got a dull headache at work around 2pm.  I had some veggies left from lunch so I sprinkled them with salt and it helped lessen my headache. (surprisingly they tasted good, usually i don't add salt to my food). 

My friend suggested I eat dill pickles if I get a headache, she said the sodium in them helps a lot...I had a couple pickles when I got home and it did make the headache go away!  Poof!
