It's normal to have fluctuations in LDs and in recall.

But for the moment, I would stop with the alarm and go back to what you were doing when you had all those LDs. BTW, are you still excited about the whole LDing thing? It's important to have intent and be excited about it.

DEILD is a wonderfull technique. Keep using your mantra for it and be patient. Best time to DEILD is when you spontaneously wake up from a dream and you remember to not move. Alarms may work for some, but in general, they jolt you too much awake. Happy dreams
