Doing a WBTB makes WILDing a lot easier for most people, because they are tired and have woken up right before the REM cycle (ideally). As far as other things helping you succeed, diet is one. Peanut butter has been known to increase dream vividness, also B-6 supplements and foods rich in B-6 vitamins work.

I can help you out more if I you tell me specifically what you are having difficulty with.
