I sleep 10 hours a night but still need to nap constantly during the day. Even 400 mg of caffeine doesn't buzz me, it just makes me feel 70% close to my normal, high energy 20s self. My daytime fatigue is so severe I've been mistaken for being drunk (even though I don't drink), and I experience a dream like brain fog around friends unless I use caffeine pills to seem present.
I know this is part of normal aging for a woman in her 30s, but it's frustrating to constantly need naps when I haven't even done anything. Sometimes you just have to biohack. Still, I feel a bit jealous of how men age differently and seem to keep loads of energy.
As someone that takes adderall (prescribed ofc), I would recommend not taking it to stay awake. It's not an over-the-counter medication for a reason.
