How Long Does Valium (diazepam) Have An Effect For?
I was prescribed some valium (15mg) the night before last (for anxiety), and I went to sleep pretty much straight away. I felt fine the next morning, but yesterday evening and all of today I have felt so drowsy, I can barely stay awake! (I have not taken any more valium) Is it possible for the valium to still be having an effect almost 48 hours later?
