Pain is worse today

Yesterday I decided to make some changes to my diet. I went cold turkey with the following items in my diet!
caffeine
alcohol
chocolate
sweeteners
spicy food
Yesterday I was fine and just a little more sleepy than normal. So I took some naps. But today the pain is worse and I have a headache which is unusual for me since I don't normally get headaches. So I took a Tylenol which didn't help and then I took a OTC muscle relaxer which helped a bit. So I'm going to continue with this new diet for a couple of weeks to see how it goes and whether it's helpful in any way.
