Try not getting out of bed at all - don't even open your eyes and don't move when you wake up. This is classic DEILD technique and to do it you need to set your intention by writing in your DJ or repreating the mantra "When I wake I lie perfectly still, eyes closed, go back into the dream and become lucid". This technique worked for me. And don't worry if you wake feeling like you need to go to the bathroom - unless your bladder is about to burst you can just ignore it and go back to sleep. I do it all the time and have never wet my bed (well, as an adult.. )
