Shift Work Sleep Disorde
"This medicine does a great job! I thought &quot;wow&quot; I&#039;ve finally found something to help me make it through the night without side effects. Almost. On my second prescription I developed scattered hives. My Dr. Said take an antihistamine and try again, since it hadn&#039;t done this before. I thought that might work until I got hives in more and more places each time I took it (I only take it when needed). 
When I developed the hives in very personal places that&#039;s when I decided I have no choice but to not take it. I don&#039;t know why it took so long to cause an allergic reaction. I wish it didn&#039;t because it really does work great. I&#039;m hoping to find something else that does same thing that I&#039;m not allergic to."
