Betty, I tried a similar approach some years back. I decided to dress for at least 15 minutes every day whether I felt like it or not. I kept at it until I got a recognizable result. Did it stop my cross dressing? No. But what it did do was something very good from my perspective.
It changed my experience of crossdressing from a compulsion, something out of my control, to a habit, something very much in my control. This took away a lot of guilt and anxiety. A definite net improvement in my life.
Feel free to PM me if you want to go into this in more depth.
