Dunno about the phenibut, since you don't take it every day it may not be a problem at all. That may be where tracking would be handy, but you could look at your intake on days when you take it and see if you get a bump in your consumption. SSRI's can cause an increase in drinking too (just a "for instance"), but a particular SSRI might cause one to drink more, the other to drink less and the next one, no effect on drinking at all. So in that context, what's true is what's true for you.
I haven't heard about people taking inositol, taurine, GABA powder or L-Theanine (a GABA precursor) suddenly starting to hoover up the booze.
When you go out, try switching back to beer only for a few nights and see what your results are. Part of the battle here is to try to maintain a connection to the conscious part of your brain (frontal lobes, for our purposes) so it can pop up and vote. Eventually, as TSM attenuates the love for booze in the addicted part of your brain (the Striatum), the conscious part (that isn't nearly as taken with the stuff) will begin to win out, so you want to watch for that moment during the evening when you get that "Meh" attitude towards the next drink, then validate that by putting a halt on drinking for the night.
Also, work on breaking up the habitual part of drinking. Don't keep your drink in your hand. Try taking a sip and then leaving it in the fridge and walking away. Get up to some little thing that needs doing, 10 or 15 minutes worth, then ask yourself if you want another sip. If no, pick another task, surf the net, etc. If yes, then go back and have a sip and be aware of how you feel as you're being pulled back to your drink. Take a sip, put it back in the fridge and then find another diversion. Just keep repeating that process through the evening and keep on watching for the "Meh" moment. Recycle any delay/divert techniques you've learned in the past. They don't have to help you maintain abstinence this time, they just need to give you an extra ounce of conscious control that day. Anything that tilts the scales in your favor is fair game.
Do work on tracking and come up with a way of quantifying when you're at home, any trick that works for you will do. When you're out, take the tab and see they call out the drinks there. If someone buys you a drink, mark that down and add it to what's on the tab. It might not seem like it, but it really boosts your conscious game, and let's face it - the conscious part of your brain has gotten dissed through all of this and has gone off into the corner to eat worms. Fish it back out, encourage it, pat it on the back, feed it, buy it a coke. Keep an ear peeled for that moment of indifference towards the next drink (or even the next sip) and act on it.
