For about a year, my son has been having bouts where he's still sleeping, but is profusely sweating, drooling, sounding like he's choking and when his eyes do open, he is seemingly in pain, does not know what he is doing, talks but it is slurred and it lasts for 30 minutes. He doesn't remember any of it when he comes out of it. He is then nauseous for 3 days. It is happening once a month, every month. Doctors have checked blood sugars, the brain, the heart. They can find nothing
