Jumpy

Hi all - this is my first time posting here. I've been doing breakfasts for about a month and writing stuff down for about 2 weeks. Today I feel like I'm jumping out of my skin. And today is only the 2nd time I've used the vitamin powder in a shake at breakfast. Another post mentioned being jumpy from one of the B vitamins. Is that what's going on with me, or is it something else to do with the program?
