I hope this advice helps:
I’m probably going to say this quite a bit, but it’s best to do it the way you find works best for you.
Again, use the way that works best for you.
There are several techniques to induce a WILD. I personally do mine in the morning, as it often yields the best results. Like early early (I woke up once at 5:30 AM to go to the bathroom, get some milk and go back to sleep. That induced a spontaneous WILD.).
If you want more specific advice, I said this in one of my earlier posts, and I’ll say it again:

Your heartbeat tends to go faster when you are excited. When you get excited, sometimes you can lose the lucid dream. I’d say no.
You lay in whatever position works best for you. As long as you’re comfortable with it, you can use it.
Keep your throat hydrated by drinking lots of fluids. I often find that drinking milk and eating apples/bananas at bed time or very early in the morning will help boost my odds of lucid dreaming.
Good luck!
