Steer your efforts towards DEILD. Yes, DEILD is a WILD technique, but it will not interrupt your sleep or make you more tired at work because a DEILD attempt only takes a minute or two of your time at most after waking up (not counting the lucid dream). Also, DEILD does not require any day work or remembering dreams.

What DEILD does require is the abilities to identify the moment of waking up while immediately remembering to DEILD, and to enter back into a dream while remaining self-aware. The identifying the moment of waking and remembering to DEILD part is mostly a matter of being motivated to do this. The entering back into a dream while remaining self-aware part is mostly a matter of finding something to focus on that will allow you to stay asleep and remain self-aware long enough to enter a lucid dream (a minute or two at most.)

DEILD is a fast technique and does not require any day work or remembering dreams, so it is the ideal technique for your situation.
