Well here it is im 15 years old and i weigh around 160lbs 5'8. Right now im on intuniv and trileptal and recently came off celexa after being on it for 2 years i felt like it did not do much anymore. I have beens struggling with adhd (not realy), depression. I have switched and been on alot of medications including the first one adderall which i gained weight on. After being chubbie and coming off i became normal reasonable weight and was happy. And no all of a sudden im 160lbs. An ideal weight was 146 but it just came on. Im not sure if its weight gain from the medicine or not? So i guess the real question is are these drugs known to cause weight gain or weight loss? And if i where to come off everything will i return to my normal weight?
