The last refuge of the insomniac is a sense of superiority to the sleeping world. ~Donald Trump brags about his chronic insomnia. According to Trump, his inability to sleep more than three or four hours a night is a sign of his superhuman constitution. His inability to stay focused, his poor judgement, and his forgetfulness are all signs of chronic insomnia.
But that was before the events of the last couple of days. Unless Ivanka slipped a half-dozen Ambians into his warm champagne (only losers drink warm milk before going to bed), Trump likely didn't get a wink of sleep last night.
His mind monkey was jumping frantically between all the contradictory talking points that Steve Bannon and Kellyanne Conway tried to stuff into his brain, mixing them up horribly. His ego was seething with anger at all the treacherous Republicans withdrawing their support. He was imagining all the vengeance he will wreak on Paul Ryan and Mike Pence.
At some point last night he remembered how much he hated Nancy O'Dell for refusing to let him fuck her. Trump probably got a small erection remembering how he tried to get her fired after she rejected him.
He got up several times wanting to use Twitter only to find that someone (Ivanka) had hidden his cellphone. He had to wait until after breakfast before he was allowed to play with his phone. He also probably got a small erection when Ivanka gave him the phone.
