Without kava, I might still be abusing benzos or alcohol. Work life? Well I finally have one now. Social life still needs some work, but I'm hoping the kava will help me make some strides against social anxiety. Not that it will completely fix the problem, but it will bring me to a level where I can do the work. Sleep quality... I still find it difficult to sleep for long, even with kava, but I can take naps on my days off.
Kava really improves my life in general and without it, I likely would be looking for something that would end up being more dangerous.
