Warfarin Sodium and wks

I'm 39 and have been on Coumadin for about a month. Was diagnosed with DVT in right calf after taking Yaz birth control for only about 4-5 months (no other pre-conditions - I'm a non-smoker, fairly active, not overweight, no recent airplane trips or long car rides.) I was on Yaz to treat severe problems with my period which has been the case since I was a teenager, but I was tired of having to call in sick to work every month, and had hoped Yaz would eliminate that problem. I had been on other BCPs when I was in my 20's, and never had any symptoms of clotting, so didn't think that it would be all that risky to try again, despite me being slightly older than the typical woman on BCP. Obviously, I am not taking Yaz anymore, and will not be able to take any other hormonal therapies for the rest of my life. But I guess that's minor compared to the risk of developing PE from an undiagnosed blood clot.

Anyway, I've been noticing I've been getting sudden, severe headaches since starting the Coumadin. I have a history of migraines but I usually only get one or two per year at most. Now I've had what feels a lot like a migraine twice in a matter of a couple weeks. My husband has also commented that I've been irritable and acting "spacy".

My INR has also been all over the place. They've been alternating me between 5 mg and 7.5 mg per day. For the first few weeks I was right where they wanted me - between 2 and 3, but then last Friday my results were 4.6!! Way too high. I go back this afternoon to see if anything's changed over the weekend, after skipping a dose and then doing 5 mg Sat. and Sun. I do hope they can find the right balance and don't have to keep tinkering with the dosage. I'm wondering if that's what's contributing to the headaches. Maybe if they can stabilize how much I'm taking from day to day, my body will adjust.

I wonder if anyone "official" is tracking the number of DVT/PE patients that can trace their onset of symptoms to Yaz. My sense is that this is a much more serious and prevalent side effect than their marketing dept. would like to admit.....

I have noticed changes in my memory, and felt very fatigued when I first started the warfarin.The fatigue has tapered off after 5 months but I notice more changes in memory lately. I get off the med in one more month. I found the best way to control drug levels is to eat at least one frozen meal a day with a lot of vegetables, such as a Lean Cuisine that is advertised as having twice as many vegetables as a regular lean cuisine...then I eat dinner and limit leafy green vegetable intake. I'm also not positive of this, but sometimes it is harder to control when I drink a lot of green tea. Hope this helps someone.

I take 7.5 mg. of warfarin daily, and have been for about 5 years. The biggest problem I have is dizziness, the inabilty to concentrate, vision, and waking up at night, everynight. I am a healthy 54 year old male, and have regular test run twice yearly.
