I got a bit confused here.

There is a difference between Instant "3 in 1" coffee and Nescafe instant coffee.

3 in 1 coffee are the ones with sugar and cream in it I think and the Nescafe instant ones are just from processed robusta beans.

I personally drink like on average 2 cups a day and during exams up to 6. For some apparent reason, lately I have been getting minor headaches and rapid heart rate. Although I do see it as a great source of anti oxidents though.

P:s Feel free to click on my sig, I wrote a story about coffee. More personal rather then Informative. thanks
