Back in his office on the morning after his night battling Sir Hugo Drax at the bridge table at Blades in Moonraker, James Bond is feeling the effects of his alcohol and benzedrine consumption of the night before. He then seeks relief.
His headache was still sitting over his right eye as if it had been nailed there. He opened one of the drawers of his desk and took out a bottle of Phensic. He considered asking his secretary for a glass of water, but he disliked being cossetted. With distaste he crunched two tablets between his teeth and swallowed down the harsh powder.
In Thunderball, after recovering from his 11 whiskies and soda from the night before, he also turns to Phensic.
Bond swallowed down two Phensics and reached for the Enos.
Apparently when James Bond has a headache, he turns to Phensic, a product that is a combination of aspirin and caffeine. Also mentioned in the second example is Enos – I’m assuming he’s referring to Eno – an effervescent heartburn/indigestion remedy consisting of sodium bicarbonate, citric acid and anhydrous sodium carbonate to neutralize stomach acid.
