"One of the major side effects that I have experienced is a total abhorrence to cigarettes.  As a heavy smoker for almost 40 years and who has tried to stop many times, I was amazed at how easy it was for me to quit once I started on Zytram (Canadian name for tramadol).  To this day, I have no wish or urge for a cigarette and find the smell to be repulsive."
