I have cut coffee before, and I slept a lot and just became unproductive.

giving up extra caffeine=death

I drink coffee maybe once or twice a month lol :) 

i have a cup of coffee everyday.  it's not bad for you at all.  i don't see the point of all this stuff since i get all my daily "everythings" ...daily.  I don't drink soda or consume anything else with caffeine either.  coffee is a little luxury in my opinion.  sometimes i drink tea instead.  but never more than two cups.  in maturity comes moderation ?

All this "detox" and fad diets and such are a bunch of bunk anyway. What do you do when they are over? Gradually drift right back into your old eating habits, which will eventually bring whatever "toxins" right back into your system. Otherwise there would be no need to do it over again and for longer times. The human mind is an amazing thing...

Eating a well balanced diet, in moderation, with lots of water and regular exercise, is the right combination for almost anyone. Easy to say, hard to do. "Moderation in all things" is the key. Want coffee? Great! Have one or two cups throughout your day, not three four-cup mugs. Mixed drink? One or two, depending on body size. Not enough for you? Re-examine the reason you are drinking...socially or are you self-medicating? Vegetables, especially dark leafy ones, are great for us, as is fresh fruit (if you can find it not drenched in preservatives and pesticides) and lean meat: fish, chicken, venison (extremely low fat, low cholesterol), grains, skim milk (most of us don't need the added dairy fat). 

Eating in moderation, 5 or 6 light meals a day, evenly spaced. If you must eat the traditional "three meals a day", do it backwards, make your large meal breakfast, medium meal lunch, and supper should be a light snack. You aren't going to work hard and need the fuel at night when you're asleep! Using vitamin and mineral supplements may be beneficial to you depending on your individual circumstances.

i think i would go crazy if i had to give up coffee for a day or 5 days.  i heard that coffee is good for you though.

ive never heard coffee's good for you. i think even the coffee companies have given up on that one. im giving menergy a go at the min, dunno if it's gonna do anything at all. But i think the best thing is to get a decent nights sleep and then I'm refreshed in the morning. I have breakfast which is suppose to give me energy later on and then i go outside for lunch so im not sat at a screen all day.

There have been lots of studies to suggest that taking a break from your desk at lunch and getting some oxygen in your lungs gives you bags of energy for the afternoon.

rich.

When it comes to coffee, easy does it. First, don't go cold turkey on a work day. Secondly, don't go cold turkey. Start mixing decaf with your regular stuff. A little at a time. It will wean your dependence. Once your at half and half, its a lot easier to go full decaf or go without. Its a shock to full strength coffee after that and for me, it makes me nauseas. So I always do half-caf.
