"mydayis works great if you are on the right dose.  i noticed some people on here are not getting the right strength when converting from vyvanse or adderall. to the person who&rsquo;s doctor switched you from 70 of vyvanse to 25mg of mydayis - your getting less medication! that&rsquo;s why it&rsquo;s not working for you. you should be taking 50mg. you will notice a  big difference!"
