Would like advice on phenibut usage for my anxiety.

Throwaway for obvious reasons.

Background: I've gotten really severe constant anxiety over the last few months. I've been on two medications from my doctor....probably ex-doctor at this point....but niether helped. The first time I asked for something non-addictive, but it just made me feel sick and have really messed up thoughts. I stayed on that for about a month, on and off as needed. After that, she gave me a benzo. It didn't really help much either, and she would only give me a very low dose.

It was getting severe at that point, so I asked if there were anything else we could try, and her answer was essentially, "No, go see a psych, I'm not giving you anything else." (psych is not a good plan, just take my word). This is odd because I've never been addicted to anything, and I've never even asked her for anything like this stuff. I don't even use benzos recreationally....but the general impression I got was that she thought I was asking for them because I already was an addict.

That aside, I've been thinking of picking up some phenibut to use once or twice a week to toggle my alcohol usage with, or maybe even mix once or twice in moderation. I'm asking for basic advice....how much to start with and how frequently, if/when to expect a hangover, backblast, or withdrawl symptoms, how long they last, that kind of thing, and how to avoid withdrawl.

I've tried researching, but the opinions vary too much. So let me give my intents:

I'm just under 90 kg (200 lbs.), and my intent is this: i want to not feel anxious, just a calm would be good. I would, if i could have it, very much enjoy a light buzz on it, but I don't want to be high or anything.

Thank you for any advice....
