Woo hoo! Congrats! I just had my first "on purpose" LD and I did the same thing: got all excited, wasn't sure what to do, and then woke up, all excited. I think we'll be able to stop waking up the more we have.

As far as the smoking and recall, you know, I'm pretty new to this, but I've observed over the years of just trying to remember my dreams that I don't think drinking or whatever matters as much as just the amount of sleep you get. That's totally my personal opinion, but when I notice that I haven't been remembering too many dreams and I think back, then I realize that I wasn't sleeping as much.
