"I Was Only Taking Nucynta For 3 Months, And Had To Switch To Another Narcotic Pain Med Because Of The Serious Side Effects.  I Had Terrible Anxiety Attacks Which Required Me To Take Xanax.  The Absolute WORST Side Effect That I Had Were The Hallucinations...I Thought I Was Going Totally Insane!  I Have A Friend Who Takes This, And It Works Well For Her, But I Must Have Been Allergic To It! "
