It completely depends on the dosage and the person. For someone that does not ingest caffeine on a regular basis, it may take minutes to a few hours to have an affect. What are you doing to the caffeine that it makes you high?

I went almost a week with only a couple 30 minute naps.  It depends on who you are and how much energy inducing stuff you drink normally.

It is true that Caffeine pills will suppress your appetite But, don't take them no longer than 2 WEEKS. And, I know people who will take caffeine pills instead of diet pills becuase they are alot cheaper in price.

That would require decaffeinating.  I'm not prepared to go to such an extreme.  But since I know that almost every other chemical flushes out of your body in 24-72 hours.  I would go with 24-72 hours!

24 hours - you won't feel the effects after 6-10, but it will still be in your system for atleast 24.

Yes- they contain insane amounts of caffeine and you should be sure not to take them within four hours of the time you intend to go to sleep, and preferably six.

You should drink a bit of coffee. The strong, bitter taste along with the caffeine will stir you awake, but it isn't recommended to drink it often. You may become dependent on it as a source of energy (physically dependent).

Maybe, but it's not likely, the amounts of sugar you describe are pretty minimal, especially compared to the amount of caffiene in the coffee you're having it with. Some people are sensitive to sugar, and when they take too much of it they become hyperactive for a while, then irritable and tired, but pretty much the same thing can happen with caffiene too.\nI'd say you have a long way to go from 8 teaspoons of sugar a day before yuo can really say you have a problem with sugar...

NoDoz.  It works wonders, kept me up for three days without wanting sleep.  It does make you urinate, though, as it's caffeine based.

Not long, it's one of the drugs that goes through your system quicker.

Most drugs actually take 4-6, sometimes even 8 weeks before the FULL effect is in swing, though you will feel some effects by 1-2 weeks.

Are you referring to that 'diet tea'?  How long ago did you take it?  Without knowing the details of your situation all I can say is to be careful and -please- don't try to 'make it work' by drinking even more: that stuff takes maybe 6-12 hours to work, but when it does kick in ... um, well, I'm guessing you'll be happier if you stick with just the one cup and see what happens.

Caffeine is in no way fattening. What i do is drink my coffee black with no sugar etc.. It only takes about 1 to 2 weeks to get used to the taste but once you do you will never switch back.\n\nBelieve it or not many bodybuilders drink Black coffee prior to competions. Go for it just do not add suger or any dairy etc...

Well, you need to be persuasive, so you need a great argument.  I have an idea, take asprin and Cola and combine to make an easy to take headache medicine that works faster because it's liquid, tastes great, and the caffeine speeds the asprin to relieve faster (like Excedrine or Bayer Back Relief)..
