I don't know whether it'd be possible with binaural, but how about something to stop you from feeling hungry?
I was sat in class today, stomach rumbling and thinking if only I had something on my i-pod that'd stop me being so hungry. Plus it'd help people lose weight. In fact, that'd be amazing if you could actually do that... a bit like overweight people getting hypnotherapy.. you'd save lives, I-Doser! Think of that!
Thanks in advance you loverly people.
