Yes, and with autism in general. By obsessed, I mean I will read any books on it that I can get my hands on (the problem is, there are too few) and I keep thinking about it almost all the time - I imagine how people with autism behave, how their minds may work, how I would interact with my child if (s)he were autistic, I analyze traits of my own which could be related to AS, etc.
I deliberately verbalize a lot in my mind, in order to get used to thinking in words, make my own emotions clearer for myself and increase my self-awareness; so, right now, a lot of the verbalizing is connected with autism. I usually take some experiences I had, or ways in which I commonly behave in certain situations, and try to describe them, then try to describe why they may be connected to autism/AS and how do they make sense to me.
This has happened with practically any strong interest I've ever had - I've been obsessed with bipolar disorder for a year or maybe more upon being diagnosed - so it's no surprise.
