If your family has alcoholism that bad you have te gene to be prone to addiction my man. You need to be careful with benzos they work similarly to alcohol releasing GABA I mean kinda not fully . You're gonna like it dude , Valium is also a muscle relaxer kind of and very sedating I'm tapering off of it right now .. And like everyone said , 4 mg Ativan is a lot breh 15 mgs Valium will probably feel more than what the conversion table would show you , meaning 15 mgs Valium = 1.5 mgs Ativan but you'd feel it more like 2-2.5 mgs ativan if it's the first time you're taking Valium it always hits you harder when it's been long time . Enjoy the buzz, but to be honest I wouldn't spread it out the half life is already insane it's 200 hours Ativan is like 7-8? So don't spread it out try a medium good dose and it takes 2-3 hours to peak . Have fun and smoke some herb if you like herb , it makes the high x10
