Roadrunner is right to mention the possible health risks to you by this behavior. I would suggest that you and your husband be checked by a physician to determine the state of your health.
Sorry to sound harsh but your husband must be told by someone who knows (the doctor) what possible health consequences could result. It's simply not fair for your husband to continue to risk your health in this way, let alone his own. You have every right to demand that he stop.
I wish you both well during this time. Hope you will continue to post as there's lots of good on this board.
