If this were the 50's or 60's one might have taken a Dexedrine and then washed it down with a Gin & Tonic. But then one also might have put their baby down for a nap on any other occasion and walked down to Betty's for a cigarette and a drink. I'm not sure June would have done either of those things but it may be why she was always so damn chipper! Of course I'm not assuming any women did these things, I just believe everything I see on TV.
Instead, I myself, put on the kettle and never get around to having that nice warm cup of tea... until hours later when they're all finally asleep! But just the thought of having a cup of tea sometimes helps!
