i was on saphris for a short time, im sorry though, i cannot give you any advice bc it didnt really help me, just made my mind kind of fog. you could possibly talk to your son in the morning, and at night, talk him through his day, he could have a fear of being alone at that college, a sense of not being near you perhaps, but try as much as you can, bc being there for him is the best medicine you can give him, lonliness can envelop even the toughest.
