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.


If you’re taking 400mg at noon, you’ll have 200mg in your system at 6pm, and 100mg at midnight. 100mg+ in my system by bedtime will negatively and noticeably affect my sleep in those situations. You could be exhausted due to the time you’re consuming caffeine
I only take caffeine pills occasionally. Not every day, and when I go through a long period of not having them I’m the same.
