I was on 300mg for OCD laterally so 25mg is nothing. I don't know about Risperdal but I know clomipramine made me sleepy at night, a dry mouth, disinterested in sex and constipated. I also sweated a lot more than others. You will burn easier in the sun too. You might put weight on, I didn't really but some people can. Risperidal didn't work for me, I got really depressed on it, and lost a stone in a month just from not eating. The OCD got really bad on it too.

Good luck.
