Today starts the blood tests I have to take because I'm taking Coumadin for my irregular heartbeat. This week I have to be tested every day to find out how much of the medicine I have to take. After that, twice a week until November 12th! Coumadin is a blood thinner and because of that if I cut myself I'll bleed more and I have watch for signs of internal bleeding. Coumadim is fun stuff, isn't it?!
