I've started taking this recently and so far I really like what I'm experiencing. I've only been taking it for about a week, so I'm only using small dosages (~ 4 grams) and slowly building up to the 12-18 grams that's advised. I didn't really notice much the first few days, but the last couple days the effects on my SA/depression have been undeniable. They are subtle, yet completely evident. It certainly has not eliminated my anxiety, but I've noticed that the anxiety is nowhere near as severe as I would expect.
For example, today my friend contacted me to go to a festival that I didn't even really want to attend. Normally, as soon as I saw his text, I would have either made up some excuse not to go or waited some time to respond... however, today it just did not feel like nearly as big of deal as I'd normally make it out to be. I didn't even really think about it and just went! There were loads of people there but I felt more relaxed than I normally would the whole time I was there!!
I'm interested to see how this stuff works as I get up to the higher doses. Right now, shortly after I take it, it gives me somewhat of a "spaced out" feeling but not enough of one to make me non-functional. It's just as if I'm not spending as much time thinking about things, but rather actively doing things. That's a big change for me lol.
PS: I guess I should also point out that I'm taking 500 mg of L-tryptophan before bed so that may be enhancing the effects to some extent.
