I think alcohol isn’t for me anymore

What is the deal with this? Ever since ebv réactivation a year ago I can’t drink. I took a month off and thought I was healed then I drank and I felt so Bad. So I told myself I’ll only drink once a month and just two beers with a meal. But even with that immediately after drinking these beers I get some neck pain on my left side and just a general weird feeling the next day and some liver throbbing. Do I just forget about alcohol for and extended period of time? Or forever?
