I’m really worried my friend is destroying his health with daily heavy drinking (about 1.17L of alcohol every day) and I don’t know what to expect next

My friend (30M) has been drinking heavily for about 10 years, and for the last year and a half it has become daily drinking. He drinks around 1 to 1.2 liters of alcohol per day. I really care about him and I’m honestly very worried about his health and future.
His situation is getting worse and he also:
takes prescribed Adderall every morning for ADHD
barely eats (sometimes skips food for long periods)
either sleeps almost not at all or will crash and sleep up to 13 hours
smokes heavily (about 1 to 2 packs per day, very frequently throughout the day)
is under extreme financial stress and debt
has lost his driver’s license twice due to DUI-related incidents
had an epileptic seizure last year while driving (first time it ever happened)
recently spent about a month in prison and was sober during that time
is now released
He also has serious alcohol-related health concerns. He was told at one point there may have been alcohol-related damage to his pancreas or liver, but later said a doctor told him it had improved or healed. I don’t know if that’s accurate or if he is minimizing things.
From what I can see, he drinks every day and seems physically dependent on alcohol. If he doesn’t drink, he starts shaking and feels like he needs it.
He just got out of prison after being sober for about a month. I’m really worried and wondering, in cases like this, is relapse almost inevitable or do some people manage to stay sober after something like that?
I’m trying to understand what the realistic medical risks are if he continues this lifestyle long-term. I really care about him, but I don’t know how urgent this situation is or what usually happens in cases like this.
