Thank you for your response. It is alot to take in especially when I dont know everything going on with him. He is on his way to a facility to detox under medical supervision. His sister drove up here to take him since he gets angry with me. He was so mad but I know it will pass.
Im not sure why this happened so many times. Ofcourse he says it didn't but his sister will let medical staff know.
This forum helps so much. I cant express how nice it is to have someone respond. Thanks again
What you describe definitely sounds like he had a seizure. I'm not familiar with Heroin withdrawals causing seizures, but it is associated with withdrawals from Benzodiazepines.
I've seen dozens of seizures during my work history ranging from Petite Mal, Startle Seizures, Absence Seizures, to Grand Mall where their arms go out into the cross position and their face turns blue.
A seizure in itself isn't life threatening unless you fall and hit your head on something on the way down. It's impossible to "swallow your tongue", but there is some underlying cause that needs to be looked into. He's not having an OD each time it happens though.
I'm not a doctor, didn't stay in a Holiday Inn Express last night, and can't diagnose your BF. Only advise that he needs to see a doctor. The next time he has one I would go ahead and call 911 even if he looks alright.
