I've been prescribed phenibut for almost 3 years now for anxiety and sleep. Lately I've noticed I need more to get the same effect, and if I miss a day I get this awful rebound anxiety and can't sleep at all. I don't take extra beyond what's prescribed, but I'm scared to even miss one dose. Is this dependence, or is it something more like addiction? I don't really know where the line is anymore.
