Generally, people are studying at night. So, if you feel sleepy, then first my suggestion is that you should have to take the minimum amount of food because if your stomach is filled with food, it feels you sleepy at the time of the study. The second suggestion is that where you study, there should be proper lighting to help you not feel sleepy at night or any time. Then you should have One water bottle for your refreshment it helps you because when you are feeling sleepy, you should drink water, and after it, you are filled with full energy and its help to concentrate on your study and not feel sleepy.

If you are studying at the time of the morning, then it is the best time to study because in the morning our mind feels fresh and stress less after that, you should have to take a 10 min break after 45 min. Why am I saying after 45 minutes, you should have to take a break for 10 minutes? 

Because according to science, or you can say by the scientist, our mind can concentrate on one thing only for 45 minutes after this our concentration will be brake and if our concentration brakes then we will feel sleepy while studying.

And another reason for you are not studying or feel sleepy at the time of study is that which subject you studied is interested or not? 

So for this kind of problem, you should have to follow the rule in which you should have to study interesting subject when you feel sleepy, and when your mind is fully fresh or not feeling sleepy at that time, you should have to study the subject in which you are not interested or those subject which you feel it is hard for you.

And you have to think that why are you feeling sleepy at the time of study? Because when you are playing or do another activity in which you are interested, you did not feel any sleepiness. So, what is the main reason? 

The main reason is that my friend, you feel study is not for you. You think that it is not interested, yes I have also accepted this thing. Still, you should be interested in your study and make the task for study and believe me, friends, this makes your study interested, and if your study will become interested, you did not feel any sleepiness. And after this, you loved your studies.
