The thing that sparked it up for me, was having a random lucid dream. I was horribly suicidal and really stopped caring about DV, and LDing for 3 months, i essentially forgot about it. Then started doing random RCs when i started feeling better, and have an LD, in late January and have been back since then, and have had many LDs since that. Try to stay determined to get back into it, and you will hit a breakthrough and be like "OMG WOO LUCID DREAM YA WOO "
