How to increase mental performance?

During exam period, my brain automatically switch to the sleepy-all-the -time mode as a natural mechanism to protect me from harm... "Exam stimulus" send a signal to the hypothalamus of my brain and thus trigger the negative feedback mechanism n results in the inhibition of my waking up cycle... So, i guess it is not reeli my fault that i failed to stay awake n study..

Prophylaxis has to be taken to prevent this auto-mechanism that 50% of the population suffer from... common age group 15- 25. male n female equally affected..

How to stay alert at night?

I've tried a lot of methods to try n counter this mechanism which surprisingly is only triggered by exams..

Ish..my friend suggested mandi air sejuk, or exercise, jump about, or simply choose the right time..

1am is the most sleepy time of the day in a normal human..So from 1 - 2 am try to do stg not that boring (study)?

1) The conventional method that most would prefer:

Randomised controlled trial proven to be useful

Pros: cheap n can be easily bought over the counter..

but after using for long term, the body is now immune to it...

2) Cheap tesco energy drink:

3) Newer Methods

4) Complementary Medicine

If all else fails, palliative measures can be taken to make the patient die at ease...
