Brief Summary:
Sleep Disordered Breathing (SDB) is a spectrum of conditions spanning from Simple Snoring to Severe Sleep apnea. SDB has multiple underlying mechanisms. Some portion of patients have issues with upper airway dilator muscle control; and such patients may be amenable to upper airway muscle training exercises using neuromuscular stimulation techniques. The investigators and others have published on the topic of neuromyopathy in the upper airway, defining a subgroup of OSA patients who may be amenable to training exercises. Based on this background, the investigators seek to test the hypothesis that upper airway tongue muscle training using transoral surface neuromuscular electrical stimulation may have benefits to patients with Simple Snoring.

Arm Intervention/treatment
Experimental: 4 Week Snoozeal Use
Participants will take the device home and be required to use it for 20 minutes morning and night every day for at least 4 weeks. The SnooZeal records usage time to allow assessment of compliance.
Device: Transoral Neurostimulation Device (Snoozeal)
Use of the Transoral Neurostimulation Device for 20 minutes, morning and night, every day for at least 4 weeks.

Primary Outcome Measures :
  1. NREM EMGgg [ Time Frame: 6 hours ]
    Genioglossal muscle activity as measured by two 25 gauge needles each containing a Teflon-coated stainless steel recording wire (<0.1 mm in diameter with ~1 mm at the tip bared of Teflon and bent to form a small hook) placed perorally 1.5-2 cm into the body of the genioglossus muscle.

  2. Change in percent total sleep time spent snoring [ Time Frame: 6 hours ]
    Time spent snoring divided by total sleep time as determined by Polysomnogram

Secondary Outcome Measures :
  1. Sleep Quality [ Time Frame: 10 minutes ]
    A self-report questionnaire, titled the Pittsburgh Quality of Sleep Questionnaire (PSQI), asking several questions to determine quality of sleep over the past 1 month that will be scored and added together on a scale of 0-21.

  2. Daytime Sleepiness [ Time Frame: 10 minutes ]
    A self-report questionnaire, titled the Epworth Sleepiness Scale (ESS), asking subjects to rate their probability of falling asleep during different situations on a scale of 0-3. Scores are added together to determine how sleepy the subject feels during the day on a scale of 0-24
