 Does zeolite, clean up till the light, cause drowsiness? One of the first times I took it, like I just noticed that right away, I was way too tired, I really didn't like it. But then I started taking it more towards bedtime and I had more, no issues with it. What could be something that you kind of like take as a natural remedy on purpose to help with sleep. There's definitely been a lot of people reporting online. You can go ahead and Google it that zeolite does cause drowsiness. Now it could be the fact that it's like, moving a lot of heavy metals around or it's like kind of giving me a big detox. It could be that kind of effect too.
