"wellbutrin did nothing for me and strattera caused erectile dysfunction and significant sleep disorders.  my doctor slowly increased my adderall xr dosage until i hit the &quot;sweet spot&quot; which was 30mg for me.  40mg made me a little jittery and anxious.  in the correct dosage adderall has improved my quality of life with no side effects.  i should note that if i miss a day i am fine but any longer without it and i become lethargic - so remember to refill your prescription as soon as you can so you don&#039;t run out.  i take the generic of this drug and it works great."
