Benzo taper with herbal remedies

So I’ve been taking klonopin 1.5mg at night for about 3ish months. Due to my sleep anxiety, prior to taking benzos I tried passionflower and chamomile. I’ve also noticed the 1.5mg of klonopin hasn’t helped the way it did at the beginning.. so I also take about 300mg of Cbg/cbd combined and it’s able to keep me asleep. But I’m going to have to taper soon, and I’m trying to look for herbal alternatives that I can take with my klonopin while I tapper. My psychiatrist told me it’s safe to drink passionflower tea with klonopin, but everything I’ve read online says to not do it. I’m a bit torn, I used to use cannabis until it caused panic attacks is.. currently I take magnesium glycinate 200mg And l theanine 100mg in the morning to keep my anxiety at bay.. so I don’t have to take more klonopin.
