You can try autosuggestion. This is an easy, incredibly effective technique that can be useful for a lot of lucid dream goals.

To do autosuggestion come up with a short sentence or phrase that sums up your goal, in this case try "I will wake after every dream." Repeat this to yourself a bunch during the day. The more you do it and the more thought you put into it the faster it will work. I suggest repeating it about 15 times each time you walk through a door way. While you use the bathroom. While you wait in line or have any "down" time. Repeat it some more while getting ready for bed, and finally while laying in bed. Think about it while you repeat it. Get excited about it. After a while (often in 2 days to 2 weeks) your subconscious will get the idea and you'll start waking up after each dream.

Another way you can try is to set an alarm (vibrate on a cell phone would work well) to go off every 30 minutes during the night. The idea is that eventually the alarm will wake you from a dream and you can write it down.

I hope this helps! Good luck!
