Hi and welcome
sure what Tommy said is about spot on.
Further rather than write a ton and as, I've already written a ton on my blog I'll point you there.
First and foremost I'll suggest that you don't just read this post once, but due to its scope consider it a reference

Quoting from the opening of that (selectively):
I wanted to say that managing my INR myself is incredibly simple and takes me about 5 minutes per week. Learning to use an INR monitoring machine is dead simple (a quick video provided) and (almost) any idiot can do it. If you buy strips online they cost so little that if you are an able bodied person you just couldn't consider doing it any other way.
you won't need this bit because being in the UK you may well get them for free.
By using the Coaguchek XS I have been essentially free to travel as I wish (moved from Australia for a year in Finland, traveled to the UK and other places) and more or less unbound in any way by being on anticoagulants.
As a bonus its been really cheap, with tests costing me less than $6 per test.
In this post my main focus is on those of us who are on anti-coagulants for the fact that we have a mechanical heart valve. As I understand it there are quite a few out there who simply do not monitor their INR after their heart valve replacement, and perhaps bumble along with a fixed dose and no idea if its good or bad.
So my Valve Brothers and Sisters if you are still reading its all good news. I encourage you to go to eBay and buy a Coaguchek XS (or simmilar) get online for strips and look after your health, for your self by yourself!
In a nut shell what I do is:
- sample my blood to determine my INR
- write that down (spread sheet, but book works)
- determine if its been over time falling or rising (a graph on a SS really helps)
- make a small adjustment to my dose if needed to correct for my INR falling or rising (usually adjustment isn't needed and its better to leave it alone, more later)
That's it ... compared to a diabetic, life on warfarin is really simple.
Next I'm going to link to the "aggregation" of all my warfarin related posts. Take your time, read through as you need to, and I'm going to say that all your warfarin related questions are answered in that lot.

However do feel free to hit us up here with questions because sometimes its just easier to ask.
Lastly good luck with the surgery and when you're in recovery hit me up for help in teaching you my INR management method. Of course you will and should follow your Dr's advice (although you won't be getting much advice from the Dr) but if nothing else approaching my method in your early days will have the following benefits
- you'll start good documentation habits at the beginning
- you can start to see how it all works
- as you progress in it you'll see why their decisions were wrong and in time you'll make better decisions on any dose adjustments (which are required from time to time).
Best Wishes
