Yes, absolutely. It took me about 3 weeks, and that was without the benefit of a lot of advice.

My recommendation would be to do the normal things such dream journal, reality checks but also immerse yourself in the concept of lucid dreaming wherever possible. Read a book before bed if you have one (Exploring the World of Lucid Dreaming by Stephen LaBerge is the best), look at articles online, and chat to your friends about lucid dreaming. In fact, often it's best not to force it...by passively engaging in learning about lucid dreaming you can make your mind very receptive to it and have crazy results in days.

Good luck and let us know how you go!
