"i lived with chronic neck and shoulder pain and when my sleep became affected, i went into anxiety and depression.  i&#039;ve been on amitriptyline for twenty years and i will never come off it.  my daughter recently had pain and anxiety.  doctors prescribed medicines that sent her heart racing. she used this and one month later she&#039;s so much better.  i believe this medicine stopped the progression of fibromyalgia for me.  it also significantly arrests shingles.  the good old medicines are tried and true. amitriptyline is excellent for many things."
