The problem with SPD is that isn't recognized a thing in the DSM, so a lot of people really don't know about it. I was complaining to my ENT about my motion sickness and other issues that I have (like sound sensitivities and not feeling here all the time), and he's the one who said ohh yeah you have this. @.@ I'm not willing though to take a bunch of drugs, so I just know what to avoid and avoid them well. (That and I abuse caffeine a lot which helps...) Once you know your triggers it helps though sometimes new things can trigger you. People see it as you're like this, so you much be on the autism spectrum, but while there is comorbidity, you can have one without the other. Which is I think the reason why it's not it's its own thing on the DSM. I'm not on the autism spectrum, so I can't speak for that side of SPD. I can only say what it's like for me, which is all anyone can really do honestly. So welcome to the site. ^_^
