Are these symptoms of epilepsy? If so, what sort of seizures are they? Wake in middle of night. Building process: wake nauseous, begin getting hotter & hotter, very thirsty, try to get to toilet. Sometimes I vomit, sometimes lose bowel control then I pass out for a couple seconds. Afterwards cold & tired, just want to sleep. Passed out off stairs (only toilet is downstairs) & the last time off of the toilet where my husband found me we don't know how long later. I remember coming in and out, even showering to remove blood coming from my head. Had stitches in my head and a concusion. Happening now for 25 years. I've been tested for everything including: hypoglycemia, hyperventilation, astma, possible heart relation dismissed by Cardiologist. Passed out while wearing a heart monitor with no results. I've been tested for hypoglycemia in the middle of a passing out event. The last few years I've found the connection with alcohol makes it worse although also occuring without alcohol.
