Anything that works for sleep issues is a godsend.

For the record I have for mine:

• a humidifier
• a weighted blanket
• a jar of htp-5 pills [which metabolises into melatonin and helps with sleep]
• the mandatory water bottle
• a notebook to transcribe worries into

Which I use whenever I need them. I've also tried white noise and mindful meditation with varying degrees of success.
