Yes, I do agree with the above poster that Hydro, or Opiates in general, obviously do effect each user differently. For me sometimes actually tends to wake me up and make it hard to sleep when taken just before bed, and others on occasion just the opposite and makes me slightly drowsy . I also get occasional anxiety and Hydro sometimes tends to help somewhat, and others it almost seems as if it invokes a light Anxiety Attack. Weird!
I do not like when I must take Xanax with my Norco, obviously not very clear headed at those times....Good thing my anxiety issues are not all that frequent, but always have to make sure I have it with me, just in case...
