"it worked quite well in the first 2 weeks with a lot of things. my thought process, my mood, my socializing, getting school work done much faster, not procrastinating. then after 3 weeks on the medicine, it plummeted. i had more side effects after 3rd week when dosage raised to 20 mg as 10 mg did not work. had heart palpitation, was sweaty, muscle weakness, extremely tired."
