Lou, not sure if calling Phenibut a knock-off is appropriate. It's a prescription-only anti-anxiety med in Russia. Not sure if I'd recommend it at this point either. If you take too much, it can be a nightmare. If you take it too often, the same. If you use it regularly and then suddenly stop, it's supposed to be one of the worst experiences imaginable. Having said all that, I had a lucid dream last night about being one of the few survivors at the end of the modern world. It seemed like the dream went on for almost 2 weeks.
