I'd like to mention in the "add and then wean of Zoloft" camp, that if your DS is anything like mine, the negatives of stopping something that is helping even a little bit can be big. Once my DS has a negative experience with a person, place, or thing, he fixates on it and it can take a lot of effort to get him to give it another try and then a lot of repeated successes to then outweigh the negative experience. Something like this resulted in DS's behavior ruining some budding friendships and a lot of acting out to avoid going to one special at school.
Unfortunately, these are really tough decisions with no guidebook and we can only really know if it's a good decision or a bad decision in retrospect.
