She has Valium.
I suspect you are thinking of Ambien, which would be a bad idea for this. I suppose it’s possible, but would be very unusual to have a doctor prescribe a nightly benzo – Ativan --which are highly addictive if used regularly.
For what it’s worth, I think Valium is pretty strong. Ativan, for me, was much, much weaker. Klonopin is a very good medium for me. This seems to vary for people in terms of which drug works best.
