I mixed benzos and ethanol lots of times. The main issue is not to forget ethanol is far more dangerous than benzos, so keep an eye on ethanol intake, as you will not overdose on benzos (you can overdose due to "typical" ethanol dosage is potentiated by benzos, but this would mean ethanol overdose, not benzo). Blackouts are common. Drugs are potentiating each other, so I would advice lower your usual ethanol intake by very much and do not pop the benzo after you used ethanol, but do the opposite - use the preferred amount of benzo, wait for 1-2 hours depending on the benzo you took and slowly begin to use ethanol by titrating the dosage based on your feeling (lets say by 0.2-0.3 BAC/hour). Keep all the benzos and ethanol out of your reach, calculate the "safe" dosage before the experience and have only this amount of drugs available to you, as you can begin popping pill after pill and drinking ethanol before blacking out and do not remember you have done this the next day. This happened to me several times on midazolam and zolpidem, when I have found empty boxes of 10 pills of these drugs in the morning without remembering what happened ... It could be a disaster if I had higher concentration of ethanol in my blood, insteed of using benzos only.
