I had 3 LDs since joining DV, and it's been like 1 month. I don't RC very often, usually 4 or 5 a day. But this Alarm Clocky thing works for me, and it's pretty odd. When I set an alarm to wake me up earlier than usual, like 7:00 AM, I have a vivid dream which almost always end up in a LD. And I ALWAYS wake up earlier than 7:00. Today I put the alarm to ring at 7:10 AM, and I had a LD. I woke up at 5:30 AM, and had a vivid Non-LD after that.
Another thing I do everyday is RC when I wake up . This prevents FAs and help getting into LDs.

Hope I helped somehow. And one last question...does this happen with everyone?
