"i was on two 15 mg spanuals a day. i felt great when i began taking them. way more focused not just at home but at school too. my grades had improved tremendously. i had absolutely. no troubles with this medication. i was taking dexedrine. for a little over 10 years. due to my other meds i now take i&#039;m unable to continue to take dexedrine. i would recommend. dexedrine to an adult or child."
