hi,i became addicted to drinking beer 7-8 years ago,but from when i started to brew my own beer i drink too too much beer.i can say i drink 2 liters or even more a day.i don't know if this is too much but my family and friend always tell me too decrease it and my father says it'll be harmful if you exceed the normal in everything not only drinking beer but i don't know how much is normal.does drink beer in this volume will be harmful ? or will it be harmful in any volume at all ?
