Triggers:
1. Beer (the one true love of my life . . . )
2. Sudden stress (similar to your "strong emotions" I bet)
3. Relaxation after a stressful day . . .
Typical day: "whew, that was a tough day but I made it through it, think I'll head home and pop the top on an ice cold IPA and celebrate . . . uh, oh, is that a cloud (shadow) headed my way? Why, yes it is. Guess I'll pound a red bull and try to sleep. Yeah, that makes sense!"
I'm doing the D3. I really have no idea if it is having an effect but I feel better everywhere else. Red bulls stop the shadows. Relpax stops the big ones.
