Warfarin Sodium and hair dresser

I am a 48 year old female with a-fib. I am not overweight...just started falling apart since now I am menopausal. I've been on Warfarin for 6 weeks. My INR has hardly moved. I'm now on 8 mg and have my INR test on Monday. I started at a 0.9. Now I'm at 1.20 and have been there for three weeks in spite of upping the warfarin. I've not changed my diet except to exclude greens and green tea when I began the therapy. Everything else is consistent.
I just started exercising again a week ago. Something I haven't done in five years since I lost my sister. I bought a Total Gym and enjoy it. It has helped me get some energy back, has helped alleviate some of the mental fog, and has lowered the incidence of anxiety attacks. (I've been getting anxiety lately...since the mental fog and memory lapses...that bothers me since I love to read and write and the mental fog seems to be taking the joy out of it now.) The reason I decided to start strength training again is because of the joint pain I have been experiencing lately. I didn't have it before warfarin. I do now. Only one joint, though. The strength training does help, but every once in awhile, that sharp pain comes back to visit. It's just a little less now.
I plan to tell the doctor that I have begun strength training again. Not just because it's good for me and my heart, but it seems to help with the side effects of menopause and warfarin...without adding another drug like an antidepressant.
Warfarin...I believe is a life saving drug. BUT, I have to do my part too.

BTW, if I didn't have triple thick hair, I would complain about hair loss. Right now, it's a non issue for me. Just saves money at the hair dresser.
