Everything you posted are things I've learned over my 45 years of wearing aids.
What you have learned is valuable to other new users and even those who hear fine but don't understand what hearing loss is all about.
Our hearing fluctuates due to many things like stress
,caffeine and climate changes. I have always needed many adjustments and fine tuning.
You can help others and be an advocate for yourself.
Good for you for giving aids a second chance and finding a website that can help you.
If you have any questions or new info to impart, I would love to hear from you .
