"i have taking 20 mg and must say that it&#039;s the best medicine for me. i can concentrate, feeling peace in my mind. i&#039;m also bipolar and before elvanse i tried medicine concerta and ritalin which made me more depressed and when they was going away from body i felt like awful. elvanse is just a miracle medicine, i don&#039;t feel when it goes away. the only side effect of medicine is : dry mouth, not feeling hungry. don&#039;t forget to eat and drink water because if you don&#039;t do it your bloodsugar will go down and you gonna feel ill,bad,headache !! i recomend this medicine !"
