Can I drink alcohol whilst taking diazepam?

It´s not a good idea to mix booze with benzodiazepines, believe I have done it and it has been a big mistake.

diazepam ↔ Alcohol (Ethanol)
Moderate Drug Interaction
Using diazepam together with ethanol can increase nervous system side effects such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. You should avoid or limit the use of alcohol while being treated with diazepam. Do not use more than the recommended dose of diazepam, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medication without first talking to your doctor.
