Also used to enjoy Phenibut quite a bit. Felt a bit like Alcohol without the "stupid". Although the onset time wasn't the best to handle and there was huge difference whether I took it on empty stomach in the morning or at some point later in the day. Haven't done it for a while though. Sleep was also amazing. Easy to fall asleep and so sweet. Definitely shouldn't use very frequently like you said. Best to leave at least 2 weeks inbetween. I had periods of using it every day.
