Don't wory to much about how long it takes you. The longer you expect it to take you the longer it likely will. Some people get there first Lucid in under a week, some take months but I bet it wont take you to long to get your next lucid since youve already had one. I've found that I wake up just as refreshed after I get a lucid dream. Weed and alchohol definitly make it harder to become lucid.
