Ok guys need some help (dont we all!)

I can lucid dream fairly regularly when I can be bothered, used to do a lot of the energy exercises in Robert Bruce's books etc but not so much anymore, I know I have a natural talent because this sort of thing runs in the family, but I CAN NOT FOR THE LIFE OF ME GET MY ETHERIC BODY TO SEPARATE FROM MY PHYSICAL BODY. And it's really starting to piss me off!

I've read most of the tutorials on here, doesnt seem to work, anyone have a really strict regime to try for a few days? I'm off work for 3 weeks because I'm going overseas so I have plenty of time.

Any thoughts?
