Yes, fluoride is a common block to intuition. Please remove all fluoride from your diet and do a detox, if you need. Fluoride can be in toothpaste, dental visits (unless you specifically say, "please don't use it" or see a biodentist), your water supply, even naturally in green tea (moderation of green tea is probably fine!)

I have found this to be a block for channeling with people consuming fluoride.

Here is the Fluoride Blog with Fluoride detox video.
