Been drinking every night for about 3 years now. For the past couple months I will randomnly get nauseous after consuming just a couple drinks. Face isn't flushed and it usually fades away after about 2-3 hours regardless if I continue drinking that night or stop. I haven't thrown up from the nausea. I had acid reflux when I was younger, although i haven't taken medication for it because the symptoms subsided for the most part about 8 years ago. I'm 22 years old, male. I go through a fifth of bourbon in about 3 days. Is the nausea caused from damage to my liver or is it just my bodies way of rejecting the liquor. Also I only eat about once a day and it's at night. I'm 135 pounds
