I'm not sure whether you're asking for advice on how to hide empties or asking for advice on how to not have to hide them anymore. Carol says you're seeking sobriety, so I'll go with that. It's funny in a way that we all hid our bottles and thought we were being so clever. Fr Martin, in one of his tapes, talks about how he used to bury them. In fact we fool no one. Why I bothered to hide the empties is beyond me now, as everyone was aware of the fact that I was drinking.
You need to stop the insanity. I recommend you go to a few AA meetings. You'll meet a whole lot of folks just like yourself who used to think they were fooling everyone. They'll also show you how to get sober.
