I love coffee.... and i love sugar. i take more than enough sugar in my coffee.... some people say that they love black coffee without sugar, and i tried that once, and it felt like the most horrifying thing i have ever tasted.
but too much coffee interrupts my sleep, so i had to bring that down to one large cup every day.... i have never tried decaf, now i think i will
Yeah it kept me up a bit. I could feel it when my heart beat haha
