I was thinking:

5 days on caffeine, 2 days off caffeine in a week can be ideal.

The problem that I found is that if I drink caffeine on weekends (aka use coffee 7 days), the tolerance grows further which results in poor performance the next week.

What do you think?

Is there a better way to optimize caffeine usage to get it's max effects?

I know about the basic facts like using it only when you need it, etc.

From my experience, investing in longer sleep and rest, and more optimism for the day help more than coffee. Sometimes a cup of coffee is like an energy loan. You get energy for some time but you have to pay it after that (more tired than you would have been).

At any rate, it's better to drink only when needed the most, not according to a fixed schedule.

I can't accept your answer. I asked how to use caffeine effectively - not how to get "more energy". – Tool Jul 6 '13 at 18:02
@Tool You said "the tolerance grows further which results in poor performance the next week." So you wanted high performance. – Mohamad Fakih Jul 6 '13 at 19:08
I'm pretty sure my performance is zero without caffeine. I'm not sure why yet, but until then drugs are the way, which is the reason I'm trying to optimize the usage. – Tool Jul 6 '13 at 19:57

See the article Caffeine: A User’s Guide to Getting Optimally Wired. It recommends consumption in small, frequent amounts. Between 20-200mg per hour may be an optimal dose for cognitive function.

You should also know the downsides of caffeine usage.

I find it difficult to keep to small amounts, so my usage tends to increase and increase until I start to get heart murmurs, then I cut it out entirely for months or years at a time...ymmv – Rory Alsop Jul 1 '13 at 11:03
I would not take 200mg every hour! My optimal caffeine intake is 100mg for the morning and 100 mg for the afternoon. Seems to keep me going through the day. – Gaʀʀʏ Jul 1 '13 at 13:16

Caffeine metabolism differs among individuals, so you'll have to find your own strategy.

I take an interval of at least 5 days (or more) of no caffeine to maximize the effect of caffeine. Even a decaf will have an effect once your body's homeostasis returns to no-caffeine state.

As mentioned above, the best use of caffeine is no-use.

In other words, you really ARE better off without it.

And, since you're asking, the more you stop it, the more it is effective when you REALLY need it.. such as if you have barely slept in the night..

Hope this helps again..
