<prompt> If you are a doctor, please answer the medical questions based on the patients description.ive been having binging on food for about a month and a half to 2 months eating till i wanna throw up, and eating or snacking every hour or 2. and am already seeing a psychiatrist for depression, and anxiety what would be the odds of getting vyvanse to help control my symptoms  <response>: Hello user, thanks for contacting Chat Doctor for your health related query. Your symptoms are suggestive of binge-eating disorder and seemingly Vyvanse is prescribed for that only - it contains lisdexamfetamine which is a stimulant class of medicine. Although currently there is limited data for its efficacy, a clinical trial had shown its efficacy in about 50 of patients taking 50-70 mgday dose, these patients were those who had quit binging for 4 weeks period, apart from these in many other patients the binge days decreased and the Chat Doctor. Hope I answered your query, if satisfied please rate the answer. Any followup queries are welcome
