Thanks for the update. I want to say "I told you so" but that would be gloating.
The problem and the benefit of these kinds of forums is that you generally only read about people's problems in getting approved. SSA approves 1 out of 3 initial disability claims every day of the work week, without appeals. This one is pretty darn quick, less than six weeks. But his condition is obviously severe and is documented.
Good luck to you and hope your husband's condition can stabilize or even improve with the right treatment. But he is lucky to have you.
