January 2009 was the month in which I had my eureka moment too. Unlike you I still dont know whether it's going to work, but I can see my idea failing as well now. This time last year however, I was almost convinced I would be winning a Nobel Prize.

Seriously, I remember having sleepless nights back then, so full of excitement. I remember not wanting to take a plane for vacation, for fear of an accident and not being able to see my idea through. And I remember accidently copy-pasting my idea into Google, and being so mad at myself for having spilled the idea to a possible competitor.

I've always considered myself a very sceptical person, always questioning things and very down to earth... and yet for a long time I was so crazy and obsessed about this idea that I almost dropped out of uni (I have lost a year).

You said that many have probably gone through something similar, I don't know about that but if so, I would love to hear from them too. I enjoyed your post very much! Thanks!
