I admire you for admitting that you have had Hypo's requiring assistance, I can understand peoples reluctance to tell DVLA about their Hypo's, but what happens if you have an accident because of your hypo, god forbid no one gets killed, could you live with that for the rest of your life? I used to not tell them until one day I was called to a RTA (I used to work for the Fire & Rescue service) where the driver had a hypo and went into a coma at the wheel. He suffered very serious life threatening injuries which resulted in him dying a few days later. His family was devastated to say the least, but they did know that he had suffered Hypo's which required 3rd party assistance on many occasions. Luckily no one else was involved.
I gave up my licence because of my type 2 diabetes and that I have serious problems controlling my hypo's, also I have other medical conditions which delay my reactions so I had to either lie or ask myself if I could live with it if something happened...
People say the rules need updating, but do they.... all DVLA is doing is trying to make it safer for people and not only other road users but for you as well.
Others may not agree with what I have said, but I am asking you consider your options carefully before making any decision.
