Hello Rose:
My 19 yo has been on 600 mg of Serequel for a few years now. I think since the age 16. I did not see him start to gain weight until the dr put him on Symbax last Thanksgiving but then he lost it real quick. Men are so much different. My 14yo however gained 20 lbs over the holidays on it. She began to look swollen and being a dancer that was horrible for her. I know how hard the extra weight works on you both physically and emotionally.
