Oh me oh my. Does this sound familiar, been there and doing that
I agree with Bina, don't miss a dose, it may cause you to get on a roller coaster ride.
Take half a dose tonight, that's right, cut a 5mg in half or take 2 - 1mg tables if you have them and start tomorrow with 4mg and alternate the next 7 to 10 days with 5mg and 4mg.
Try using this, it may help

Thanks for the dosing calculator Freddie! My coaguchek is on its way, so I hope to use this soon!
