Used to avoid coffee for a long time, now drink 2-3 cups/day. It really helps me to wake up at the morning if I didn`t have enough sleep. Sometimes, coffee is extremely useful. At the end of the working day I often feel tired, but one cup of coffee instantly gets my energy levels back. That`s pretty much the reason why I started to drink coffee - feel better and get more shit done on a daily basis. But yeah, since I started to drink it regularly it always seems like an addiction, especially at the morning.
