I do not follow CAD/CALP, so I am not very familiar with it. However, strict LC causes me to have episodes of extreme moodiness, so years ago, another LC'er recommended I read Potatoes Not Prozac. a little pumpkin or potato before bedtime made a huge difference!

Now that I'm diabetic, I don't want those bedtime carbs, so I take 5-HTP (a seratonin precursor) a couple of times a week and get the same affect. I know if I start getting irrationally upset, it's time for some 5-HTP!

So it totally makes sense why some added carbs work well for some people.
