Steve man be carefull with that drug Sotolol..... its been proven to cause prolonged qt syndrome which can bring on lethal arrythmias.... is that the only choice of med you have for your A fib?? you might want to talk to your doctor and see if there is other options... perhaps get and ablation to cure the problem... or at least talk to your doc to see if there are other drug options.... as far as your headaches I have the same problem with the Aura's and im fighting hard to come up with a plan to stop this problem ..... I also have been getting Aura's since childhood and sometimes I wont get them for a year and sometimes I'll get them 2 times in a week....... after the Aura comes the headache.... sick and tired of dealing with it....
