Im 28 been drinking every other day to get drunk 6-7 pints lager for 5 years and 1 year every other day. so heavy drinking. ive quit and started healthy eating and exercise. can i still heal and live a long life?

Likely yes: It is likely that your liver will repair itself, unless there is fibrosis. If you quit drinking permanently and adopt healthy habits, you should have a normal life span. Your doctor can ascertain if there is irreversible damage in the form of fibrosis. Have a healthy diet, exercise 30 minutes/day, drink plenty of water, have safe sex, no tobacco alcohol weed or street drugs.
