I've never tried the TILD(thirst induced lucid dream) technique before, but I've heard of others who have. I just wanted to point out, that if you have no success with this technique after a few tries, don't bother with it anymore. It can be unhealthy to make yourself thirsty before bedtime, as it could result in dehydration, seeing as your not drinking a few hours before bed, and then top that with sleep time, it adds up to many hours without any water. I especially wouldn't try it EVERY night. If you want to keep trying, separate it between days, for example, every other day.
