Consider, if you will, that the feeling you call "pink fog" is not, in fact, euphoria at all. At least that's not what I found for myself. Suppose, for the sake of argument, that in your daily life, when you aren't dressed that you experience a general discomfort, or depression, sadness - a dysphoria - that is hard to detect because you've never felt differently until you began to present as a woman. In other words you are simply experiencing happiness, or feeling right about yourself, something you haven't felt often before. There is strong incentive to continue doing the thing that makes you feel less dysphoric.
I don't believe this is an addiction. I am a recovering alcoholic and my feelings of gender dysphoria were orders of magnitude stronger than my alcoholism. Indeed dysphoria drove my addiction. This is the reason I transitioned. I'm not suggesting y'all should, but that something akin to a less intense version of the gender dysphoria I suffered from affects you.
