I have not much experience with cbd but it seems like a nice addition to me.

While some like it, there are also people who don't feel big effects from it. I don't think it will be as effective as benzos in terms of anxiety relief and fear but i might be wrong on this one. I don't think it will make sn less effective. Paradoxically it might make you throw up so ae is always recommend to increase reliability. First-hand experience with cbd will be the only way to know for sure whether its a good addition i would say.
