Hi all, Just looking for some advice. Have child (age 12) with Aspergers (coupled with adhd) diagnosed at an early age. Has been on medications for a few years (Concerta) which seemed to be helping. Also being treated for anxiety which is a side of aspergers. Was put on Zoloft for past 2 years. Experienced continual weight gain. Took off stimulants for 6 months but suffered in school so started Focalin recently. Seems to be doing better. I want to take off zoloft because I believe it caused the weight gain. (Child is very sedentary which doesn't help). Mood is very blah as well. Not sure if puberty or medications. doctor wants to change to prozac. Any advice is appreciated!
