insomnia
"My doctor prescribed mirtazapine 15 mg. every night at bedtime to replace the Ambien 10 mg. due to all the hoopla about combining Ambien with opioid medications.  So far the mirtazapine has NOT been effective in giving me a full night of uninterrupted sleep like Ambien did.  Also I have to weird/bizarre dreams since taking the mirtazapine.  When I talked with my doctor about it, she prescribed another sleep aid that has a copay of $156.00!!  So I will have to settle for what the mirtazapine offers as I had to choose between Ambien and my narcotic pain medication for my chronic back pain.  Sigh..."
