Alcohol abuse and diabetes are a deadly combination. If those two diseases don't kill your brother, the smoking will. Heart disease (seen it), emphysema (seen it), cancer (seen it), amputation from diabetes (seen it), etc. Your brother is on borrowed time. If he wants to save his own life and you want to help him, the time is now. Period. Bring him to a hospital and have him look at an emphysema patient. Hands and feet swollen from the fluid retainage, skin blue and splitting from the pressure, having your lungs pumped so you don't drown in your own mucus is one helluva sight I guarantee no one would forget. Take him to see some diabetics that have had their feet and legs amputated. That's where your brother is heading, especially with alcohol abuse. I wish you the best and hope he'll save himself if he really wants to.
