Hello and welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
Adderall contains a combination of amphetamine and
dextroamphetamine.
These are
central nervous system stimulants that affect chemicals in the brain and nerves that contribute to hyperactivity and impulse control.
From your description i deduct that you may have a condition called
Narcolepsy.Adderal is indicated for the treatement of Narcolepsy.
Considering this fact,i agree with your doctors for the sleep studies.
The polysomnogram (PSG) and the multiple sleep latency test are considered essential in confirming a diagnosis of narcolepsy and will be very helpful for the right treatement of your actual symptom.
If the sleep test confirm the diagnosis of Narcolepsy,than the amphetamine-like stimulants(Adderal)in the right dosage or antidepressant drugs are very important to treat your persistent exhaustion.
If the sleep test exclude the diagnosis of Narcolepsy,than i suggest to do the thyroid test(
TSH,fT3 and fT4) to see if you have
Hypothyroidism.
Hypothyroidism or low thyroid is another condition that can cause
tiredness or exhaustion and can give an explanation for your symptoms.
In this case the thyroid
hormone replacement therapy will help you to treat your persistent tiredness.
Hope this is helpful.
Let me know if i can assist you further.
