PIP bloodthinner??

Currently I am taking 5mg of Eliquis twice a day. Since all my afib episodes occur only at night, why can't
I just take a daily dose before bed? I am a CHAD-Vasc score of 1. For protection during the day, I would
supplement with NK or consume fresh Natto.

Any insight on this?

Your stroke risk extends beyond the period when you're in active afib. In fact, the point of highest danger is the period after afib has converted back to NSR. Although your risk is pretty low being a CHADS 1, it's still higher than someone who doesn't have afib. The trouble is you have no way of knowing how effective your plan is, nor how it might interact with the Eliquis. All in all, you'd just be rolling dice in a high stakes game without knowing if your plan is more effective, less effective, or downright dangerous. Not sure what you're trying to accomplish.

There's no guarantee with Eliquis is there?
Natto does a lot of other good stuff besides thin blood.

How often do you have afib?
