I'll be keep it short, but I their computer said "yes"S88 MAY apply to you, because your conviction was before June 2013.
Can you confirm exactly when you applied this time for your licence back?
Have you had any acknowledgement from DVLA?
What happened when you did not do your medical last year… what did DVLA say to you?
In 1999 were you just convicted of drink driving
or were there any other offences?
Has your GP said that he / she has no concerns about you driving? (You need to ask, not presume)
Short answers would be appreciated as I find it hard reading your lengthy posts!
