I've already started using melatonin microdose to adjust my sleep schedule, have started daily fish oil, and am looking into possible nootropics that fit within my (extremely limited) budget; so it's not a bad overall thought.

However, the ad copy on that sleep mat includes 'acupressure' and 'meridians', which immediately sets off my skeptic's alarm bells. I suspect I'd do better to finally find a decent zafu pillow to sit on when I meditate.
