Adderall
"I'm 24 years old and have taken Adderall over the course of 10 years. I know the only side effect I couldn't control is the stunting of my growth. I'm 5'7" and I only grew 1/2 inch in high school. I'm given 90, 30mg monthly. It has always improved my grades, however knowing that tolerance builds I do not take it all the time. Remember you have to take care of your body, especially your heart and liver, because long-term use side effects are still not concisely known."
