When my Grandfather had a stroke and was moved into a VA hospital, they made him give up smoking by force cold turkey. He was dying and they made him give it up completely right there and then. They wouldn't even let him go outside to smoke. EVERY time I talked to him, all he wanted to talk about was having a smoke. He died within about a month. It ticked me off then, it ticks me off now. I thought it laughable that they wouldn't give a dying man his last wish... Cause it was bad for his health.
Same thing happened to the founder of Alcoholics Anonymous.
Friends of Bill failed him at the end (for the same reason, BTW).
Sorry for your loss.
