I find that those who can’t do without coffee are addicted to the stimulant.
In my opinion, any kind of addiction is bad. As a test of will-power, I’ve told some friends to do without coffee… but they can’t even do that.
It seems like human/animal nature is very prone to addiction.[/quote]
I can say that in the past I was definitely addicted to caffeine. I had some physical problems and my doctor told me I had to stop the caffeine, so I did cold turkey. I had caffeine withdrawal headaches for 2 weeks. Very painful. That’s why I still say it’s more than just willpower. I’m pretty sure I have strong willpower as I’ve given up many different foods/drinks. But your body does have its way of protesting and physically letting you know its objection to the deprivation of what it is accustomed to enjoying.
In the past I was so addicted to caffeine, I could have some in the evening and have no trouble sleeping. If I have any now, I am wired. There will be no sleeping until it is out of my system. I can really feel the effects on my nerves. It does not feel good.
