Fatigue in ASD/ADHD

Medical science cites 6 hours as the least amount of sleep in a 24 hours period. Autistics may well need 8/9 hours. Sleep affects medication and performance.

It is proven that autistics get more tired than the average person.
This is easily understandable since every task requires extra planning and decision making.
I need at least 8 hours of sleep to function, while 4-5 hours is the norm these hectic days.
People pretend to get used to it, despite evidence having long shown how lack of sleep weakens the Immune System and shortens life-expectancy, yet I often feel ‘lazy’ even if I put up long hours at work.

Fatigue is not laziness.
My cause of Fatigue is Anxiety, which in turn triggers Insomnia.
Insomnia is debilitating to me.
That leaves me with two options: double up my meds or call in sick. 
The former is the most likely, though not without consequences the likes of hypertension, encephalitis.
Thus far for ADHD meds.

Avoiding triggers and proper rest is paramount for all.
Regular sleep is crucial in Mood-stability.

Stimulants are the meds of choice for ADHD through enhancing dopamine, the main neurotransmitter involved in reward and motivation.
Reward and motivation have an antidepressant component.
People with ADHD must take them anyhow for studying or working.

Mood-stabilization is the ultimate goal.
We’re still far from it: antipsychotics remain the only option to date.
