Magnesium helps with feeling anxious.

They make this powdered stuff that regulates your balance of calcium of magnesium called "Natural Calm". I take 1/4 tsp in my tea at night when I'm feeling agitated.

Other than that, no idea if it's helping, but I take:

Vit B complex
Vit D
Magnesium pill
Fish oil pill

... Figure it can't hurt anything.
