or any other type of treatment...
I always get tired by the end of the scholar year and that is bad for me cause i can't concentrate myself in classes and my grades go worse...
Last year I had an excellent Final grade till one month before we finish the year...
and in only one month i received very bad grades and all the effort from the beginning went to the trash.
I know that it was because i felt tired and sleepy all day, although i slept enough and had a good breakfast.
So I was wondering...Does anyone take any pills for concentration?
Which one? (scientific name)
Or do you do any special thing like exercises for your concentration?
