I've been taking dalmane (flurazepam) in the morning with my valium. Is this safe?

No. Both medications cause sedation and cause more sedation and dizziness when taken together risk of falls or accident unless you work at night and sleep during daytime.
Dalmane (flurazepam) Dalmane (flurazepam) is a hypnotic used for insomnia, on occasional basis, only at bedtime. I have never heard of it being used in the morning. Combining it with valium is bad idea, due to excess sedation.
