"i am 19 and was prescribed a small (10mg) dosage to start me off. i took it in the morning before my classes started. after an hour i began feeling nervous, headaches, upset stomach, dizziness, and i had uncontrollable shaking in my hands and feet. the doctors are starting me on something different, but will try zoloft again at a later time. if it is your first time using zoloft i highly recommend using it after work/school. i would really like to give zoloft another try since i have seen great reviews."
