I am in a similar situation. I practiced several years ago, developed decent recall, and had 2 lucids. After the second I thought they would come with more ease, but I became frustrated and gave it up. I came back to practice 2 months ago. I started with an average recall of 1 dream every 60 days. I followed the standard recall advice and within 2 weeks was up to 1 fragment-2 dreams a night. After 33 days of RC daytime practice and dream journaling, I had my first lucid.
My advice would just be to practice RC and awareness training every day, and dream journal every morning. It will come, just be consistent and don't give up!
