i like coffee, had some problems with it one time not long ago but found out that the thing that made my eye "vibrate" when drinking coffee could be removed by intaking some b1 vitamins. so i did and have not had the problem since.. it is the muscle shakings im refering to.
I like it but i don't have habit to take it regularly. However, i will take it occasionally, depends on my mood. Usually i have it in Coffee Day.
