Having been on Warfarin and Heparin(the later should my INR fall below 3) I find of late that my INRs change daily, have the warfarin same time each night. When my IN either falls below 3.5 or higher I go woozy etc etc. I am feeling fed up because I dislike feeling like thisI cannot bear feeling out of it. I go tired etc and once I have a nap I am fine however, at weekends it is unlikely as I dont like going to sleep when my hubby is busy around the house and my daughter needs support doing A Levels. I recharge in the week. and its lovely. Does anyone else feel like this?
