I found this thread about a 6 months after I was BD'd. 6 months later my H had an awakening and he asked me what was wrong with him. I let him read this story. (copy paste in e-mail and deleted the names)
He told me that this was very similar to what he felt. Awakening was gone about a day later. Back in full fog. Don't think he still remembers any of this if I would ask him now.
Anyway, I thought it was very helpful to understand what they are going through.
