Here is an idea I just had for LD inducing capsule.
What you do is use some kind of thick capsule that melts quite slowly in the intestines.
You put in it stimulating stuff such as caffeine. You take it when doing WBTB, and when you are already asleep the capsule melts and the stimulants are released. stimulants increases cognitive activity and may help in getting you lucid ( if it doesn't wake you up ).
What do you think?
