If he's estranged, does he have a key to your home? If not, you need to report him for breaking and entering. I suggest that you work on legally securing your safety from him, which includes getting him removed from having access to your medical records and being contacted for decisions related to your health in the event of emergencies. This time his behavior caused seizures- next time, it could be worse.

As an Epileptic myself I hope that you beat the crap out of him for this. Taking meds away from someone with seizures is tantamount to assault because it is all but guaranteed the person will have a seizure that can severely injure them. Talk to a Law Enforcement officer and see if there is any legal course you can take against him, also don't let him stay your "estranged" husband and make him your EX-husband. Hoping you are well. :)

your a fucking idiot for staying with him

Wow, that is just awful. He should not have access to your home and your medication. If you have a lawyer, make sure you mention this to him/her to bring up during the divorce proceedings. I don't know if a restraining order would be out of line here, but you need to take action against him.

And that's when I would cut the brakes off the car

Is there a lawsuit in place for this kind of endangerment?

I'm almost certain that tampering with someone's medication is illegal all on its own. If it was me, I'd get the cops involved. I hope you're able to get emergency refills.

I can't find words to describe this man. Get a restraining order now and seek legal counseling. Keep your medical records and meds safe and at ready access you can't mess with seizures. i hope you soon get rid of this moron.

If you're still living together, go to a friend or family members home. Get a restraint order. Go to the DA with proof of getting new pills and possibly the ER. Just calling a battered woman shelter hotline will help

Good news! Turns out he's the psychotic one, and the cure is repeated beatings to the genitals. You can trust me; I read it on the internet.
