| Change in sleep quality by self-reported assessment via Consensus Sleep Diary - Morning Administration (CSD-M). | Change in sleep quality by self-reported assessment via Consensus Sleep Diary - Morning Administration (CSD-M). Sleep quality is assessed by a 5 category rating from 'Very poor' to 'Very good'. Sleep quality is also assessed by a 5 category rating of the degree of rested state from 'Not at all rested' to "Very well-rested' | Baseline, week 1, week 4 and week 8 |
| Change in sleep quantity by self-reported assessment via Consensus Sleep Diary - Morning Administration (CSD-M). | Change in sleep quantity, as defined as the collective amount of sleep obtained in a given period, by self-reported assessment via Consensus Sleep Diary - Morning Administration (CSD-M). | Baseline, week 1, week 4 and week 8 |
| Measure | Description | Time Frame |
|---|---|---|
| Change in quality of life | Change in quality of life as assessed by the Short Form 36 Health Survey Questionnaire (SF36) which consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability. | Baseline and week 8 |
| Measure | Description | Time Frame |

| Adverse Events self-reported by participants | Adverse Events self-reported by participants | 8 week period from enrolment to participant conclusion |
| Change in medication use | Change in medication use self-reported by participants |

| Change in sleep onset time as assessed by the Pittsburgh Sleep Quality Index (PSQI) | Change in sleep onset time as assessed by the Pittsburgh Sleep Quality Index (PSQI). Seven component scores are derived, each scored 0 (no difficulty) to 3 (severe difficulty). The component scores are summed to produce a global score (range 0 to 21). Higher scores indicate worse sleep quality. | Baseline, week 4 and week 8 |
| Change in sleep onset time as assessed by self-reported assessment of sleep quality via Consensus Sleep Diary - Morning Administration (CSD-M). | Change in sleep onset time as assessed by self-reported assessment of sleep quality via Consensus Sleep Diary - Morning Administration (CSD-M). Participants are asked "How long did it take you to fall asleep?" | Baseline, week 1, week 4 and week 8 |
| Change in sleep onset time as assessed by wrist actigraphy | Change in sleep onset time as assessed by wrist actigraphy which measures wrist movements to assess sleep or waking state. | Baseline, week 1, week 4 and week 8 |
| Change in sleep pattern disturbance as assessed by the Pittsburgh Sleep Quality Index (PSQI) | Change in sleep pattern disturbance as assessed by the Pittsburgh Sleep Quality Index (PSQI). Seven component scores are derived, each scored 0 (no difficulty) to 3 (severe difficulty). The component scores are summed to produce a global score (range 0 to 21). Higher scores indicate worse sleep quality. | Baseline, week 4 and week 8. |

| Change in daytime sleepiness as assessed by the Epworth Sleepiness Scale (ESS) | Change in daytime sleepiness as assessed by the Epworth Sleepiness Scale (ESS) which is a list of eight situations in which you rate your tendency to become sleepy on a scale of 0, no chance of dozing, to 3, high chance of dozing. The ESS score (the sum of 8 item scores) can range from 0 to 24. The higher the ESS score, the higher that person's average sleep propensity or their 'daytime sleepiness'. | Baseline, week 4 and week 8 |
| Change in restless legs symptoms as assessed by the Restless Legs Syndrome Questionnaire | Change in restless legs symptoms as assessed by the Restless Legs Syndrome Questionnaire. Ten component scores are derived, each scored 0 (none) to 4 (very severe). The component scores are summed to produce a global score (range 0 to 40). Higher scores indicate more severe symptoms. | Baseline, week 4 and week 8 |
