This is not an appropriate Other Drugs post so I am going to close it.
If you have a huge benzo tolerance, then benzos are not going to do much for you. 5mg of lorazepam is a large dosage for most people without a benzo tolerance, so I would suggest you take 2 or 3 milligrams, and save another 2 or 3 for another night. Hold onto clonazepam for later as well, you really don't need to combine the two.
Alcohol + benzos is a bad idea. If you know combining the two is OK for you because you've done it before, then just be careful and don't overdo the alcohol part of it.
Oxycodone added into benzos and/or alcohol will get you somewhat higher than not taking it, but if you can appreciate just 5mg of oxycodone on its own, that's what I would do.
Ethanol + benzos = amnesia for a lot of people, almost irrelevant of benzo tolerance. I would suggest not combining these two.
Closed.
