YES!!
I took a 2mg gummy one night, and when I woke up I was dizzy (off balance—not really vertigo type spinning) until 3pm when it had subsided enough for me to feel okay.

Note: I also have anxiety and take klonopin every morning. So maybe it doesn’t mix well with benzos.

I really need help sleeping lately, but I won’t go near melatonin. I couldn’t find many good articles on it, but searched Amazon reviews of melatonin products that had thousands of reviews. Many said they had dizziness.
