Hi Mel, I have ppms & my licence was revoked in Jan 2012, two months after ms diagnosis.
For you, it’s your job & income so I’m sorry to put a damper on your hopes but try not to rely on total success (it’s rare that dvla revoke immediately). I really wish you well in your appeal & support from medical team x.
In my own circumstances, unfortunately dvla stuck to their own medical advisors decision & wrote to my gp, more or less saying his medical opinion is not medical evidence! The DVLA explained their decision is based on my cognitive disfunction and I could misjudge stopping distances, misunderstand road signs, be unable to apply an emergency stop.
That was 2 years ago & I have to concede it wouldn’t be safe for me to drive with my hidden disability, it’s worse now, and I don’t want to risk serious injury to anyone.
I hope you are able to have the thumbs up. Good Luck x
