You were asking about appealing a CAA ruling based on previous and current problems.

FAA or CAA or DGCA it’s irrelevant as none of them would issue you a “no restrictions” Class 1.
FAA regulations 61.107 requires the following:
Substance dependence, except where there is established clinical evidence, satisfactory to the Federal Air Surgeon, of recovery, including sustained total abstinence from the substance(s) for not less than the preceding 2 years.
ICAO has 193 member states all of which abide by the same general rules and regulations as that is the whole purpose of the organization. Bar ( relatively) minor differences the rules are the same. Including for medical issuances.
