I resumed the phenibut today after a week off.
Some notes on using alcohol for the withdrawal -
I wouldn't recommend it. My plan to drink limited amounts didn't work out too well - smaller amounts of alcohol didn't seem to do a whole lot to mitigate the phenibut withdrawal and instead I ended up just drinking to intoxication for the first four days of withdrawal. Although it allowed me to thankfully pass out for 5-6 hours each night, I woke up every morning feeling like DEATH. I could tell that I was never in any danger as far as seizures or anything like that are concerned, but the mental crash from a hangover on top of phenibut withdrawal made the entire experience far more unpleasant than it had to be.
So to sum up - small amounts of alcohol for phen wd produced negligible relief. Larger doses nicely covered up the symptoms, but the next day felt like monochromatic hell. Benzos would've been a much better choice, since they lack the shitty depressed feeling that alcohol hangovers tend to give me, but I don't have access to those.
Regarding the GABA-A vs B issue I brought up in the original post - I'd now assume that alcohol produces pretty minor GABA-B activity, since I drank pretty heavily for four days and it still didn't seem to impede my goal of reducing my phenibut tolerance. I've done this phen detox four times a year ever since I decided to take the stuff longterm, and nothing less than a week is ever enough to reduce my tolerance. In the past I tried 3-5 days off and it never works - and if the alcohol I drank for four days in a row had been acting heavily on GABA-B, that would've meant that I actually only gave the B receptors three days to recover. Yet today i took half the amount of phenibut I'd been taking a week ago and I'm getting profound effects from it again. Yay.
