I wanted to share a recent side effect I've developed from using phenibut. The last few nights, I've been using it to aid sleep, but have been using up to 2g (first night was 1g, then 1.5, now 2g last night) and this morning I'm experiencing some serious aggression, however – I have absolutely zero anxiety. I did some research into this and aggression is a known side effect according to pubmed. Not good...I just wanted to share this with the forum in case people aren't aware of it. The feeling was very apparent this morning, kind of a constant, lasting aggressive feeling that's not going away, not sparked by anything in particular.
