It sounds like you're having some trouble, 5 lucids in 3 years is definitely on the low end. Are you dream-journalling every day? I ask because I reckon that you should have had more than 5 lucid dreams in that time period just from chance occurrences, training aside. It could actually be that your level of dream recall isn't great and you've had more lucids than you remember. If you get in the habit of remembering more dreams (via journalling), you'll necessarily remember more lucid dreams. Then of course there are side benefits leading to more lucidity like recognition of dreamsigns etc. Just a suggestion, you might well be journalling flat out, in which case ignore this post!
