I recall seeing others complain of similar symptoms.
If you followed Dr. McD's recommendation to also give up caffeinated foods (cocoa, chocolate, coffee, sodas, most tea, etc), then you will almost certainly have headaches & irritability for a few days. Seems to take 3-7 days for it to clear for most people. If the symptoms are too unbearable, you can go off the caffeine gradually to avoid them.
Like Bob said, make sure you are eating plenty. I'm still learning how to do this, but I am convinced he's right. It can be really hard to let yourself eat at the first sign of hunger (for me, that's often feeling irritable, tired, or foggy-brained) when you've spent years being told by the "experts" that you need to "eat less, move more" to lose weight. You will eat MORE, lots more, on this program. Especially the first few weeks - you will likely be incredibly hungry and feel like it's impossible to safely eat as much as you want. But it is. And you will still lose weight!
