Drinking coffee on an empty stomach could make us sleepy?


Question?
  Drinking coffee on an empty stomach could make us sleepy?
Hypothesis
Somebody say when we drink coffee on an empty stomach in the morning after we drink coffee 30 minutes our body will absorb caffeine to blood vessel and send caffeine to brain resulting sends oxygen to the brain is reduced. But I think something make me sleepy is not caffeine in the cup of coffee maybe it is a sugar because many doctors have to say about the negative effect of sugar. And one of them is the brain inactive down. Because sugar make an amino acid called Tryptophan being accelerated into the brain, too. Upset the delicate balance of hormones in the brain. As a result is that the cause drowsiness, fatigue, unbisinesslike and feel sleepy.
Experiment
            I do the experiment by 4 condition
1.       Drink a cup of pure coffee on an empty stomach 3 times
2.       Drink a cup of pure coffee after meals 3 times
3.       Drink a cup of coffee with sugar on an empty stomach 3 times
4.       Drink a cup of coffee with sugar after meals 3 times
Collet Data
            Collect data by count time after drink to time feel sleepy in two hours if more than two hours record that do not cause of your sleepy
                1st Condition Not cause of your sleepy 2 times and feel sleepy after drink 1.58 hrs.
                2nd Condition Not cause of your sleepy 3 times
                3rd Condition Feel sleepy after drink 1.43, 1.36 and 1.53 hrs.
                4th Condition Feel sleepy after drink 0.56, 1.24 and 1.13 hrs.
Conclusion
            From the experimental result, perhaps what makes us feel sleepy. May not be the caffeine in coffee. It may be the sugar in the coffee.
                Sugar can make me feel sleepy because when we drink coffee or drink with amounts of sugar our brain willinactive down because when our body have many sugar our body will make an a lot of amino acid called Tryptophan and send it into our brain when a lot of these amino acid into the brain it make the brain frosty after that we will feel sleepy
                But this experiment was conducted with only me. If we have many people in this experiment I think the result of this experiment maybe change. Because each person is different I believe if others do this experiment by use the condition like me the conclusion may change and the meals I eat before drink the coffee may impact with the coffee I drink after meals
                So this experiment may not be reliable because it was conducted with only me and not control the meals before drink the coffee
                Conclusion coffee can’t make me feel sleepy things that make us feel really sleepy is sugar in the cup of coffee not caffeine in the coffee but if others make this experiment like me do and control other factors that may have an impact with the experiment the result may change
