Wow this sounds all too familiar to me and I am wondering how you made out? I have DVT that needs an INR of at least a 3 and have been down at that 1.6-1.9 level and I have re-clotted in the two's. I know this is an old posting of yours but I am looking for someone out there to talk to occasionally about this condition when it surfaces. Please email back if you have any info on ANYTHING out there that is available to us. I'm doing some research on this and will take any advice you have to give. Thanks! Hope all is well!
