I've been searching the forums for something about the affects of alcohol on dream recall. I'm aware that marijuana has drastic influence on recollection. But what about couple beers?

To my understanding, alcohol does impact Non-REM sleep.

Let's say, before bed, i ingest three beers. Before the REM period, my blood alcohol content, theoretically, would be zero. Here is where the question gets hairy. Do the brain waves remain altered, or does the mind correct any imbalance during N-REM?

Also, i'd like to know about having five or six alcoholic drinks. When the BAC infringes on the REM sleep, would recall diminish greatly?
