I know your post was about natural remedies but I have read oral GABA does not cross the BBB in sufficient quantity to make any difference. However, Neurologix is working on GABA gene therapy, I believe they concluded phase II of their trial and many are waiting on those results. Phase I was apparently a success. MJFF may also be involved with Neurologix.

Paula has posted quite a bit here about messing with acetylcholine levels, you may want to review those posts.

Thanks for sharing this, very interesting. 108 is incredible to me.
