Alright, I've been trying to achieve lucidity every night for 3 months. I have only Lucid Dreamed once before, and it was unintentional. So I know what it's like, and it makes me very anxious to achieve it. Here is what I do:

1. get in bed, relax for 10 minutes by taking deep breaths.
2. I close my eyes and lay still in a comfortable position, usually for (what appears to be) ---10-15 minutes.
3. I know I haven't entered SP, so I roll over to my side, without opening my eyes and do the same again.

Now here are my problems:

1. Either I get bored and say "Ah, fuck it" or I fall asleep.

Could anyone tell me why I cannot achieve SP even after not moving for 10-15 minutes? Is swallowing fine? Is it fine to lick my lips?
