Joel, love your mantra! You are absolutely correct on passing it by your doctors first!

Flora, I initially lost 25 pounds with tafamidis but the pounds were unnecessary since I had gained 50 pounds previously. It started to bother me but I leveled off after that poundage loss. most of us could afford to lose unnecessary weight, so it is probably good. Ask yourself, what did you weigh at 20years old? That will tell you whether to bring it up with your Doctor. The A FIB should be brought to your Doctor's attention. Via the Nurse if necessary. Merry Christmas to you also!
