... was taking warfarin. I have been in AF for 2 years but since June 2011 have been in normal rythm and have been advised to keep taking blood thinners until Dec 2011 to protect me from suddenly reverting to AF I had an ablation in nov 2010. I dio not feel happy about this new drug and seem to be getting worse with stomach and I digestion also when driving I have noticed that my eyesight is slightly out of focus. I'm thinking of returning to warfarin. Any comments would be appreciated. Oct 19 2011
