I am experiencing the side effects of the meds I was put on for the A-Fib that I hope go away soon.  I haven't been on any type of medication for quite some time and I'm not sure if I should be worried.  Dizziness, and just generally not feeling well.  This seems to be an every other day occurrence.  I do have a call into my Dr. to see if something needs to be adjusted.
