Hello Friend, Good that you are seeking a help here. I am sure you are taking this tablet after consultation of a psychiatrist and he/she would have adviced you on the pro and cons or side effects of such medicine. Pls report your feedback to the doctor if you are seeing weight gain. FYI, for any psychic treatments, medicines are  just one part of the treatments to bring down your emotions under control. However, its important to follow certain non medicine treatment plan like changes in your lifestyle, dietary changes, excersise, self therapies etc to get a complete cure. It's equally important to follow such things based on certain recommendation. To get a suitable recommendations, you may need to consult a Psychologist to assess your co condition in detail. Feel free to reach out to me online through Practo for further detailed evaluation.

I would suggest you to consult you psychiatrist for better answer.
