Good morning Old Gal,
Have just logged on and found a damsel in distress so, wearing your favour on the end of my lance, I'll come riding to your assistance.
6d.
Reversed this is the past tense of 'to drink heavily' [and, for that reason, will start with 'de'] and the noun is usually associated with a drunk.
14d. The heraldic term for 'green' + anagram of 'bear' + E [for English].
12. The first word is a synonym for 'session' - think magistrates or school lunch break - and the second word [ignoring 'fairly'] is an adjective quite often associated with 'Polly'!
With kind regards,
Caravaggio
