Coffee Analyzer

I found a great site ironically on the website of a drug company for analyzing how much coffee is left in your system when you go to bed even if you think are in the clear by consuming it early in the morning.

That is a REALLY cool widget. I never drink caffeinated beverages, rarely drink decaffeinated coffee, but often have some dark chocolate. Wow! The graph is fascinating.

Thanks!

Definitely an interesting graph - What it doesn't show you is that if you have a coffee at 7 AM every morning, by the end of the week you will be getting a high level of caffeine in your system by the end of the week. Add in some chocolate during the evening, and is it any wonder some of us can't sleep?!

Neat tool but a little scary

Can you provide a reference for the week long accumulation comment I'm not picking on you, I only want to get more info.

That is interesting, but i see nothing about how body characteristics come into play. I doubt that a 100 lb female and a 250 lb male process caffeine at the same rate.

Awesome tool - - after several nights of awful insomnia (1 or 2 hours of sleep), I think I see a potential explaination for the problem. I'm gonna cut back. Way back.
Thanks very much for posting!

From their site:

Caffeine can be found in your body for as long as 8 to 14 hours after you've consumed it. This may affect your sleep at night.

Halting caffeine consumption earlier in the day will reduce the levels of the stimulant in your body at bedtime, but it may not eliminate it completely. You may still have caffeine in your body the next morning.

Many people consume caffeine products to overcome daytime sleepiness. Caffeine levels build up over time and may keep you awake when you should be sleeping at night.

If this were true wouldn't people be reaching a lethal dose at some point?

If caffeine can be found in your body for as long as 8 to 14 hours their graph is way off. They show caffeine in your system 24 hours after consuming it.
Try this, pick some caffeine source at your wake up time. Watch the graph, it never reaches zero.

caffeine is for life! like tattoos used to be

Interesting site. Even with my waking up three times a night I still get a sleep quality score of 9 (not bad).

I do miss my coffee though (2 cups of real - max, 1 cup of decaf, all by 10:00 a.m.) I used to drink the stuff pretty much all day.

Jeff, Good point. People should think about what Rozerem is and what the motives to that website are.

Of course the manufacturers of Rozerem would want to present the worst possible case for caffeine. Caffeine is the market's dominant and cheap stimulant. As long as it is widely available and cheap, Rozerem sales are going to be poor. So now they try to make the public think caffeine is a bad guy.

I asked my very good sleep doc about Rozerem. He said Rozerem works, but the problem is that they haven't developed an "off pill" to take when it is bedtime.

On his advice, I developed a practice of taking 200 mg caffeine around one or two p.m. It's a great, safe stimulant and if I get in the bed at 11:00 p.m., I fall asleep quickly and sleep about seven hours.

The calculations are quite simple. Caffeine is reduced by one-half every 7 hours for the average person (but it could be as little as every 4 hours). My reference for this is a medical APP called Epocrates. It's free for IOS users.
The calculation below show how caffeine is removed from the body over time. Each line represents a reduction of 50%.
The 14 hour line represents approximately the time from mid morning until bed time. Note that a 12 oz. cup of Starbucks coffee in the morning is equivalent a 12 oz can of Mountain Dew at bed time. Looking at other values in the table, we can see by the next morning, the amount left in your blood stream is almost the same as if you woke up and slugged down a 12 oz. can of Coke (my favorite beverage, btw, and I miss it every day after figuring out I am hypersensitive to caffeine).

Just to put caffeine in perspective in case you are sensitive to it.

This is a cool product that I backed a while ago, that some of you might be interested. Yes this link includes a referral code, but if that REALLY bothers you feel free to strip it out. I'm not posting it here to get point (though I can end up getting mine free), but because it is 100% relevant to this discussion: https://www.myvessyl.com/?referral_toke ... 48reip2WTg

Basically its a "smart cup" that actually analyzes what you pour into it, and can determine and track things like Caffeine, Calories, Sugar, etc. I can't wait to get mine.
