You ask me about brain-fog and energy levels. Both are much better. From a position of just lying around the house all day, when I started, I've progressed to being able to go for a good walk - 1/2 hour every day, as well as cycle rides every now and then, which I never would have believed possible!
Yesterday, I went to a book club event for three hours, including having to present my views on the book in question. I managed alright, although it [i]was [/i]a bit of a strain - I felt tired afterwards and my amygdala started firing off all over the place, but after a good night's sleep and a few dozen Stops, I've been fine today, whereas before, even a small social event would take at least a week to recover from. But I was able to take in what everyone was saying and enjoy it - so it was very encouraging for me. I can tell that my mental energy is still not as strong as a normal persons, but for me it was a great improvement.
I find that I have to keep my mind engaged almost constantly in some absorbing activity, otherwise my amygdala still plays havoc. I look forward to the day when I can just sit back and relax withough that happening!
I hope you manage a way to do the retraining while carrying on working. I can imagine how difficult it must be.
