I took myself off of Toprol XL last month and so far I am doing great... not one skipped beat since December. Now I'm taking Cipro for an upper respitory infection and I got over my cold in two days... Cipro is #1. Of course if my skipped beats were related to a virus or somekind of infection... it is gone now... Cipro kills everything in your system, the draw back is that it also kills your own antibodies. I feel great though. I hope everyone on this board eventually overcomes their heart condition. -God bless everyone.
