@Heliograph it’s been a long time since the top half was that sensitive to coffee
@ozeng it has never gone away for me 

@Heliograph lucky you, I feel like a functional human being with coffee. Without coffee I just feel like garbage.

I have about a 45 minute window after waking where I feel OK. If I haven’t had coffee in that time then body realises it is being conned and the wheels fall off.
