Hello welcome to HCM.
I have read your question and understand your concerns.
Warfarin works by inhibit vitamin K, and increases bleeding tendency. So avoidance of vitamin k contain foods should be avoided.

Vitamin k contained foods are -

Cabbage, cauliflower, carrot, spinach like food should be avoided.
Green tea is also not recommended.
All fortified foods that contain vitamin k should be avoided.

You should check your PT and INR every 2 monthly. In atrial fibrillations target INR should be between 1.8-2.2.

Thank you.
Have a nice day .
