Recently, my brother vomited once or twice a day because his dose of epilepsy medicine was too high. Is he likely to vomit in his sleep and choke? Or will vomiting wake him up?

I don’t know because the reaction to drugs is unique, however, since drunk people, drug addicts die from vomiting under the influence, your brother should see a doctor as soon as possible. There may be another drug that has fewer side effects. If the doctor says he’s fine, okay, or you’re still worried, see another doctor for a second opinion. Prevention is always a better thing than cure. I lost my sister because she couldn’t call for help.
