Not all all - don't even mention it
I've read so much about Greece, Cyprus and the Czech Republic on here - I didn't know anything about overseas clinics until I started browsing this forum and I find it really amazing that people share all sorts of helpful information with each other.
I had second thoughts in the beginning, but then I discussed it in several forums. People were sharing their own experiences about the clinics I was considering. I also did a research on my own and contacted many clinics, and this is how I finally decided, but the forums were indeed a great help!
