Here's another difference between addiction and gender dysphoria. For example, the treatment for alcoholism, i.e. addiction to alcoholism, is to stop drinking. The treatment for GD is, for some of us, transition - which on the surface looks like crossdressing all the time. (It's way deeper than that, but think about it - how many other addictions is the treatment to do more of what you are addicted to?)

There are NO effective or ethical treatments that reduce the need for gender expression / identity that differs greatly from societal expectations. The only effective and ethical treatments known involve:
1. Living the gender expression / identity as needed. (Often this is all the time.)
2. Therapy to help accept this part of ourselves.

That's it. There is no magical treatment to stop these feelings. Those who offer them have all proven to be charlatans.
