I've been on Coumadin 6 weeks, and have been told to expect 3-6 months total (although lifetime use has not yet been ruled out). I've been told downhill skiing is too risky while on blood thinners so that's been a major point of depression for me during this snowy New England winter. Anyone out there who does downhill ski while on blood thinners? If so - advice? Is your doctor on board w/your skiing?
