If diagnosed with apnea/hypopnea, subject must maintain use of device throughout study 18. Untreated nocturia that affects sleep Exclusions to rule out subjects with conditions that could affect their safety: 19. Females of child-bearing potential, as defined as menstruation within past 12 months or not surgically sterile. 20. Systolic blood pressure \> 150 mm Hg 21.

Exclusions to rule out subjects with conditions that could inhibit or confound the effects of MMFS or the ability of the subject to complete the study: 22. Serious or unstable clinically important systemic illness or disease that, in the judgment of the investigator, is likely to affect cognitive assessment, deteriorate, or affect the participant's safety or ability to complete the study, including hepatic, renal, gastroenterologic, respiratory, cardiovascular, endocrinologic, immunologic, or hematologic disorders 23.
