I haven't done one of those, but it sounds intimidating. However I know that many of my disability appointments took far less time than what they quoted to me. One they said 2 hours and I was in with the doctor for about 30 mins. The other time (about 15 mins for me) was filling out a form. Perhaps they allowed more time because some people need more time for the form, but certainly not an hour for two pages.

I hope it doesn't make you too miserable.
