I saw my gp today, and she was fine with me changing to Rivaroxaban from warfarin. This is an experiment to see whether it reverses my hair loss, apart from being much more convenient for all the usual reasons. (No INR checks, no food restrictions). I also asked if I could halve my bisoprolol from 2.5 to 1.25, to see if my energy level improves. I told her I was attempting to tweak my meds a bit, and she was most accommodating. Strangely, I feel quite excited at the prospect of some areas of improvement.
