Hi. Ive always had a hard time concentrating on my studies, and I see this as a big obstacle to my success in achieving good grades. Im so tired of this, and it even went that far I couldnt proceed with my second year after failing three subjects from first year. Its not me being lazy, I wake up early, eat well, excersize and do everything in order to have a healthy mind and body. It has reached its peak, and I am 100% sure some medication will improve my concentration in my studies. Can you please help me?
