Thank you so much to everyone who replied to my post re. Flecainide and Apixaban. So helpful when you're struggling.
Since coming off the Flecainide last Monday I have checked my Kardia frequently. It always reports NSR. My EP and GP insisted it was ok to come off Flecainide cold turkey. I am very drug sensitive and questioned this but in the end did as they said. I really believe that a lot of the side effects I am suffering now are withdrawal symptoms. I have searched posts on here and there are several, some from a few years ago, who identify with this and also suffered from rapid withdrawal. I am seeing my GP in 10 days and will discuss it with her but I'm sure she will dismiss it totally. Many years ago I had to withdraw from Diazapam. A total and absolute nightmare. This was also dismissed by my then GP as all being in my head but it is now recognised that a long and painful withdrawal from Diazapam is a very real thing!
So if this is withdrawal from the Flecainide I shall wait it out and hope it subsides sooner rather than later.
Thanks again to you all for the support and I wish you all good health.
