Hi,
It is not possible to prescribe drug substitute for 50mg of Vyvanse, or the drug itself without proper examination and case history. However, you can try cognitive
behavioral therapy for the mentioned symptoms, as the medications prescribed have potentially dangerous side-effects.
In addition, the symptoms like low motivation, inattention and
fatigue can happen in sleep deprived individuals. It is not uncommon in patients with sleep apnoea to experience these symptoms due to lack of quality sleep and day time somnolence.
The best treatment for sleep apnoea are to use CPAP/BiPAP and weight loss(if
overweight).
However, if you suffer from
aerophagia or other problem that makes it difficult to use ventilation; other possible treatments of sleep apnoea includes mandibular advancement surgery,
tonsillectomy,nasal EPAP and diaphragm pacing to list a few.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr. Ayesha Shareef
