I have severe anxiety attacks from PTSD since I returned from Iraq.
The fucking veterans affairs had me poppin 3 or more 2mg clonazepam/klonopin a day.
I started using kava kava...not the garbage from hawaii...the good stuff from vanatu n fiji. Google 94% Kavalactone paste...just dissolve in apple juice with some lecithin granules. Makes your mouth feel like you just gargled with cocaine

and has a very nice Benzodiazepine effect.
Kava Kava has a reverse tolerance so there's a plus...and smoking after drinking some kava is very nice
