I think there may be something in the ibuprofen effect. I took it a couple of times before I knew about AS, just to try and ease out my general feelings of physical discomfort, which were playing up at the time. There was nothing specifically wrong with me except that minor aches, pains and itches had been feeling very amplified and I couldn't screen it all out. I felt better after the tablets, and would take them all the time if I thought it safe, but I don't trust them, so I only use it as a last resort.
That's purely for sensory issues. I haven't noticed any improvement in my social competence, executive function problems, or any other autistic trait. But I haven't particularly looked at those.
