Always carry lots of tictacs.
A good topic.
I'm obsessive about my breath.
I never have garlic or curry the night before. if not going straight to a punt I have some cheap toothbrushes (25p from tesco) and a small travel toothpaste. When going up the stairs, quick squirt of breath freshener.
Pity not all WG's are the same, saw a girl recently, a smoker, by the time she'd finished snogging my face off I felt like I'd had 20 capstan full strength!
