During the 2020 primaries, he was sleepy and not with it in all the debates, but when it came time for the one-on-one debate with Bernie, all of a sudden he was "fiery" Joe.
The same thing happened at the state of the union. They literally hide him whenever they can, even to the point of him declining a pre-superbowl interview. And then all of a sudden he's "fiery" Joe again during the state of the union.
I have to believe that they are giving him some kind of concoction or drug or something, and I don't think it's conspiratorial to speculate that this is the case.
So to any biology/pharmacy/medical experts out there, what the hell is going on?
I wonder if modafinil would have much of an effect as it's mostly useful for wakefulness so it's primarily prescribed for narcolepsy although it's a second-line treatment for ADHD. Afaik it's also used by the US armed forces for fighter pilots and similar to combat fatigue.
Modafinil also increases focus, like other stimulants, though to a lesser extent. It was big with tech bros for that purpose before everyone could get Adderall prescriptions through apps.
