Scary! I have never seen a scorpion, let alone one in my own home. If I did that would surely keep me up at nights too.
I do have severe obstructive
sleep apnea so I know about sleep deprivation and being unable to sleep. I'm treated now and use a CPAP machine to breathe at night and I sleep better, but I'd prefer not having to use a machine at all.
I have personally used Valerian root to help me sleep. It isn't addictive like most sleeping pills, so it is safe to use - even on a regular basis.
Good luck and definitely do something about your sleeping issue. Your health can really decline without proper sleep.
