[Question] Paleo and autism - how long?

Ive researched about paleo a bit and seen that people can reduce symptoms of mental issues of all kinds. I have autism/aspergers myself and noticed a bit of a calming effect from paleo, but I am still autistic, so I'm unsure if it really works any better than what Im feeling right now. Is this the best I'll get from paleo? I know diet won't transform you into another person, but I thought i'd be more normal than this.

I've done the diet on and off, so Im thinking of doing it more longterm now. I'm going to give it one last try, so Im wondering how long I need to be on it till I get the maximum benefits?
