I have a suggestion.

Instead of using a totem as a reality check, like in the movie. Find other uses for it.

I have a necklace that I've worn 24/7 since I was seven years old. Even then, it never once appeared in a non-lucid dream. HOWEVER, when I am lucid I can reach for it and it is always there. I use this as a kind of grounding element in the dream, I focus on the shape and size of it, looking for any imperfections in the small metal pendant, or any inconsistencies with the waking necklace. In this way the dream becomes clear and realistic and lasts much longer. Because I always use the same thing, and it is always with me, I don't risk the usual delay that comes with inspecting other things in the dream. This also has the effect of giving me stellar dream control, but I don't expect it would work that way for everyone.
