ADHD
"I have been taking Ritalin for almost 3 years &amp; it has been great. I had ADHD in high school &amp; college. I couldn&#039;t focus, listen to lectures, read well or study. I saw a doctor during college &amp; he prescribed me Ritalin 20mg 3x/day (I had long days in college). I was finally able to read well, study &amp; focus. I love learning now, I&#039;m motivated &amp; my mood improved. Now I take 20mg 2x/day (I graduated &amp; go to bed earlier). It lasts around 4 hours. I never experience withdrawal or major sleepiness when I don&#039;t take it. Side effects: Difficulty sleeping if taken too close to bed time &amp; appetite loss (minor). I highly suggest an eating schedule and drinking lots of water so you don&#039;t eat too little. I would often forget to eat in the beginning."
