I had it last week, 4265 grafts - I'll make a post down the line when I've some progress under my belt. One thing I found helpful was looking for people who had similar hairloss to myself and viewing their results from the Dr to see realistic expectations.
Demirsoy mainly has German/Austrian clients i'm told so there are a lot of posts on non english speaking forums, for example:

Everyones situation is different, definitely do a lot of research on doctors and take it all in before making your decision.
