How much cyproheptadine is safe daily? It's not for me for someone else, they have poor sleep really bad appetite to the point they literally will eat nothing all the time and anxiety depression mainly being used for sleep and appetite , 4mg daily isn't doing much for appetite but is helping with sleep a little . Cyproheptadine Dosage Guide with Precautions - Drugs.com this website is saying up to 32mg?? I can't imagine taking that much lol but is say 8mg daily safe?
