I am so sorry for your loss. A very good friend of mine has been battling alcoholism for many years, calling himself a functioning alcoholic. A few weeks ago, he blacked out while driving and went into a ditch. Luckily, his truck did not roll over and a motorist came along at some point and called 911. When they got there he had several seizures before they could stabilize him to take him to the hospital. By the Grace of God, that incident has scared him enough that he as vowed to stay sober. I will see him this weekend and I'm looking forward to seeing my friend in a healthy state.
May your friend's soul rest in eternal peace.
