"This medicine has been great for me.  I was first prescribed a beta-blocker when diagnosed.  However, it made me so sick and sluggish that my doctor switched me to Flecainide.  He warned me not to read about it on the internet because of all the warnings, but I knew I had to do something.  I have been on this medicine for 8 years with no problems (50 mg 2x day).  It has made a big positive difference for me.  I had a headache for about 3 days when I first started, but not since.  No other side effects at this dosage."
