Insomnia
"I have had insomnia since a hysterectomy in 2009, so began taking benadryl but that had the opposite effect on me &amp; I became very jittery w/ &quot;restless leg syndrome&quot;, so tried Unisom 25mg nightly.  I have been taking Unisom now for 6 years and it has worked pretty well to help me sleep at night.  However, 2 months ago I developed a fast &amp; irregular heart rhythm.  I am a nurse, so listened to my heart and could hear the missed beats when I felt them.  It felt like I had just ran up a flight of stairs but I wasn&#039;t out of breath.  My heart was just beating very rapidly and irregular.  Couldn&#039;t figure out why I was having palpitations so quit taking &amp; saw Dr. Diminished palpitations since I quit taking &amp; all my heart tests and labs are normal."
