Doing SSILD before bed may be more helpful than it seems. Of course in the first few hours of sleep, you're probably not going to get a lucid dream. However, the SSILD cycles will still raise your awareness for those first few hours. Now, each time you wake up during the night (whether naturally or with the help of an alarm), do more SSILD cycles. Do SSILD cycles during each awakening to keep raising your awareness throughout the night.

Example:

11:00PM - SSILD cycles, go to sleep
3:00AM - Wake up, go to the bathroom, drink water, SSILD cycles
4:30AM - Wake up, maybe go to the bathroom again, drink water, SSILD cycles
6:00AM - Same

Right before you go to bed each time, you're raising your awareness so when you return to bed at 4:30 and 6:00, there will be a high chance of getting a DILD due to all the awareness training during the night.
