I wish I could tell you the answer to what is safe to induce sleep using
Valium, but I have the same question as you! I have Xanax, instead of
Valium,
and I have no idea what a safe dosage would be for me to induce sleep or that of your husband. I'm a pretty tiny woman, but have a high tolerance to all medications, so it's so hard to know what is safe! I hope you get the answer you are seeking soon, because I know I wondered the same thing!
