It is expensive. Usually 45-60 dollars for a months supply.

I’ve used the American Shaman water soluble full-spectrum and Medterra isolate CBD oil. Both were effective for me with a slight preference towards the Medterra isolate.

It’s about the most “normal” feeling I’ve ever had. Definitely by far the most effective treatment I’ve had for anxiety, and that’s including the SSRI’s. Probably beats Lexapro because of the near non-existent side effects for me. But again, sample size 1.

The /r/cbd group is a good starting place.

CBD isolate by itself can be a lot cheaper. The cheapest I've found is online from Fully Activated, around $20/g. You should be able to mix your own tinctures with liquid coconut oil, and optionally sunflower lecithin.
