Amy Gregorysmart move. If I take two, I go to sleep too fast and
  get a hangover from it. If I take it at all, I just take one.
  Tried using 1/2 dose as anti-anxiety - worked a little but I
  didn't like the grogginess even with that. (hence my obsession
  with finding things that help anxiety; Mom took me to
  biofeedback when I was 11 "Breath through your feet - you're a
  warm bottle in the sand" etc - and that stuff got me through
  middle school - actually fixed the worst of it really. But the
  left over stuff, panic attacks, well, hence a lifelong journey
  of figuring out how to fix, not just for myself, but for others
  as well. "
