Hi, I m not sure I need to ask you questions now.... I have been on Digitalis and Aspirin for about 3 months I think and Sunday I had an experience of confusion, cognitive spacing, reading and not understanding the words though they looked familiar, colored lights such as with eye strain, blind spots, nausea, basically all the symptoms listed in this artlecle. Which now I realized have occurred very, very mildly intermittently sometimes during treatment. Originally I was treated in an emergency room for what turned out to be low pottasium from too much water consumption but I had ,as I aways have a mild arithmia which never interferred with my strong purusit of s;ports and all activities, but they told me to see a cardiologist which I did; was prescribed Dig. and aspirin. I have seen my Naturopath today on a regularly scheduled appt.. and have a call into the prescribing Cardiologist. While I discontinued taking Dig. tonight I will contact my Cardio in the morning. If you have anything to add, please feel free.
