I've Been On Nuvgial 4 5 + Year's I Also

I've been on Nuvgial 4 5 + year's I also am a chronic pain patient, in addition I have central sleep apena . I'm always fatigued, I'm so tired of being tired the nuvigal doesn't work for me. I believe I have Adrenal fatigue I have 70 2 80% of the symptoms. I was wondering if Ridlin (methylthidate might do the trick ? I do take many prescriptions 13 2 be exactly plus Oxygen & I do not have a lung Disease it's because of my multiple apena what do you think?
