Hi @Insomniac and welcome. You are not the only autistic person here on Talking Sober so you are not alone 
And even if you were the only autistic person, you still wouldn’t be alone, because sobriety is a journey of learning to be healthy.
Being healthy is sobriety. It’s basically that. It’s digging into the self and learning from people in recovery, then applying that learning, little by little, to change habits of mental and physical behaviours. (Which is basically a recipe for being healthy.)
Lots of autistic people find ways to learn to be healthy, and for the same reason you can find ways to learn to be sober (which for us means healthy).
There are some books and podcasts you can start with here:
