What is name of the product?
I got checked out initially because I mentioned to my sister that I didn’t recall the last time I’d woken up and felt refreshed all day, even with 8+ hours, and she said “…that’s not good, get that checked out.”
Back to the drawing board :(
Do a full polysomnogram with MSLT: this will check for sleep apnea, restless leg syndrome, narcolepsy, and idiopathic hypersomnia
Look into ME/CFS if you have post exertional malaise (pretty much you cross some invisible line in exertion followed by a delayed crash).
Look into MCAS if you also have strange allergy symptoms. I have MCAS, though tbh I didn't really have that many symptoms until I looked at Dr. Afrin's free chapter on MCAS.
Maybe fibromyalgia, but you didn't mention muscle pain, so it probably doesn't apply.
Obviously depression can cause somatic symptoms, so that's worth checking, but I think people jump to that conclusion too soon.
Note that a lot of these conditions don't really have tests, so it's really tricky to get a diagnosis. It takes finding a doctor who's willing to recognize them and give a diagnosis.
