I have a moka pot but I guess I am doing it wrong -- maybe I should not fill its coffee compartment to the brim? is there other way of doing it? -- because the coffee that gets out destroys me: heart palpitations, slight arrhythmia, headaches, and energy crash. I can't drink too much caffeine but light doses (i.e. the Americano) actually help me and energize me. It's really weird.

What's good about the aero-press and the French press btw? I am only just trying to understand the landscape.
