How to Talk About Hyperfixations Less?

You could write or draw about it for awhile before talking to him, he could leave the room for a little while, or he could get noise cancelling headphones or similar to wear while he needs quiet time that way he can give you a visual sign that he needs quiet and it also cancels out any other noises that could bother him. Infodumping can be an important part of bonding and it can be depressing to not do it, I hope he can understand and you come to an arrangement that works for you.

The way this was phrased instantly gave me chills. It can be hard to distinguish between lessening how much you talk, and silencing yourself. Instead of trying to do the one, maybe spend some time in different rooms? You can't chat their away off if they're not in the room. Just an hour or two of quiet could work. It's just so hard to find the balance. I tried, once, and I never found it until I went entirely silent and didn't even try to talk about my interests anymore.

Firstly, its okay to want to info dump, its one of the things our brain does when it’s happy. In terms of keeping it at bay, genuinely try writing stuff down, thats what I do sometimes when I am somewhere I can’t talk out loud like in a lecture or something. Other than that try to keep your hands busy with a fidget or something to expend the energy. But don’t bottle it up or you will feel really burnt out, you just need to find ways of getting out the energy and excitement

Ok don’t condition yourself, you’re being yourself. Maybe try and be more conscious of others, but conditioning yourself is not the word I would use. I tried that, it just made me depressed, because you can’t condition away autism.
