Hi,
I voted NO.
I was discharged on day 7 (that's a privalage we have here). On day 3 I guess I could cope with the training BUT at that time I was still at my "baby" stage. I was focused on very basic functions of life, getting out of bed, walking (all the way to the doorway...), eating, sleeping, showering and so on. I don't think it would be fare to expect me to concentrate on INR testing at that stage.
When I got home I wanted the agent ot come, and I had the motivation to take responcibility and control. The agent came with the thing on about day 10, that was perfect.
By the way, is your tester sold/supported in Israel?
