Hi and welcome.
I only drank beer and then wine. I couldn't stand spirits. I would very often go days, weeks, sometimes a month of so without alcohol. All of this convinced me that I was not an alcoholic. But I am an alcoholic, now in recovery.
It's the problem that alcohol causes in your life and your lack of control which determines if you are an alcoholic (only you can decide for sure). If you need to give up or restrict because of health concerns now and for the future and can't do that, then you are certainly a problem drinker. I found that moving from problem drinker to alcoholic happened very quickly without me ever realising. If you are not an alcoholic, you could be very close to it.
Take care.
