"mine may be a somewhat rarer case of adhd, that is very severe, and my response to amphetamines is almost perfectly paradoxical for the best known effects.  i sleep better and longer with significant blood concentration (it&#039;s neutral for going to sleep, but keeps me asleep longer), have better appetite, cannot achieve euphoria or a &quot;high&quot; from amphetamines, only a mild feeling of extra energy.

for me adderall is far less effective than single ingredient d-isomer formulations.  best guess is that the l-isomer is what ruins it for my condition or perhaps the more exotic salts.  vyvanse, desoxyn, dexedrine are much more effective and without side-effects for me.  didn&#039;t expect the difference, but adderall doesn&#039;t work well with my brain chem."
