Well I look at it this,way if someone is giving up something that they have been eating and drinking for quite some time there is sure be some withdraw effects, especially sugars and caffeine because they are stimulants that your brain is conditioned to having, so basically when you give something up you are training your brain to do without them .For some people it is very very difficult and to some a bit easier because some people have more tolerance.to withdraws., ,Tolerances to withdraws is the key to success to eliminate cravings for anything be it drugs alcohol, smoking etc. I always take the approach that there is no such thing as perfect diet, a prefect life, a perfect food or perfect anything so you have strike a balance, after all one has to enjoy some things in life so you have assess how coffee is effecting your well being. I tried giving up coffee and tried giving up cream in my coffee, and it was major difficult, i got headaches, dizziness and tiredness, so what I did was gradually do little things, like pour a tiny amount of coffee out of my cup and then add a tad of hot water then a tad less cream, then I would add tad of decaff and so on, this small gradual decrease did not effect me one bit and after doing that for some time I got to the level of coffee consumption I wanted, now I can enjoy a coffee and I could not imagine not having a coffee and I can not imagine having cream in it, but I now put tad of coconut oil in my coffee to take away the bitterness and I look forward to having my coffee, I don;t think having a coffee is going to destroy your life, enjoy
