Cannabis+WILD?

So sometimes I have trouble going to sleep if I haven't toked a bowl before bed. But usually when I do it I crash out pretty hard and don't remember any dreams. What if I set an alarm for maybe 4 hours after I fell asleep and attempted a WILD. Would smoking earlier in the night have any effect on succeeding with a WILD?

There has been many threads like this and many have the same results.

Doing weed or hashish will lower your dream recall and chances of lucidity.

Here is a thread that tries to address the same question:
