Hello. My brother wakes up several times during his sleep with a feeling of wanting to vomit, but what he actually feels is that he can't breathe. Sometimes this is followed by a seizure. He has epilepsy now for at least 6 years and is taking the generic for Keppra twice a day. Someone told my mom it could be acid reflux, but I don't think that is true. Maybe it is sleep apnea. Any help? Thanks.
