I tried CosmicIrons SSILD and think it has real merit. I am fairly experienced having had over 125 LDs and usually LD once or twice a week. Tried SSILD and had a semi-lucid the first night I tried it...two days after last lucid. Not definitive but did have a lot of vivid dreams as well as an LD. The technique makes sense and felt right for me. I like having something intentional to do that indirectly affects dreaming...too direct and it becomes self will which usually doesnt work.
