Agreed with Erii.
However, if you've been trying hard for a long time, perhaps a break would be best for you. Just two days would suffice, just not even worrying about dream recall. Get some great sleep and go back at it after that.
On the other hand, how long are you keeping at these techniques for? The habit of keeping up your awareness (for me) doesn't kick into my dreams until two weeks after I first start it.
Have you tried Puffin's SAT Technique?
