I'm curious if you continued taking the Kavinace and if it remained effective for your pain. I have taken it for anxiety and sometimes it helps and other times it doesn't.

I'm not sure about Taurine for sleep, but it does have an effect on GABA and everything is all tied together in the brain. I was actually advised to take straight GABA for sleep.

Interestingly, the GABA apparently crosses the blood brain barrier in some people and not in others. So you can take it and if it makes you sleepy you have the right physiology and it can actually be a very effective sleep aid. I will find out soon if it works for me. Any anti-anxiety effect would be an added bonus as this is much cheaper than Kavinace.
