Could 22, 2015 #3 The effects actually count on the dose. I've quite a bit of working experience with Phenobarb, And that i find that in modest doses, about 50mg-60mg, it has effects really similar, to Diazepam, and In general very monotonous. Even so in doses of 100mg+ it gets a lot more enjoyment. It appears like staying drunk with a clear head.B
