Hi, I understand your concerns after reading your question. Co Quetiapin is an atypical antipsychotic medication that can be used to treat schizophrenia and certain types of mood disorders. Like other antipsychotic medications, side effects are common. Increased appetite and consequent weight gain are well known side effects of CoQuetiapin. Other side effects can include sleepiness, increased blood lipids, increased blood pressure which may be related to weight gain. If you experience disturbing side effects, you should talk with your doctor who who may either modify the dose or change the medication. I hope this helped you.
