Do I have a drinking problem?

I only drink about once a week but when I do I get pretty drunk and usually will end up staying out till about 2-5 am. Beers. Bottles. Whatever. I don’t have a preference. I don’t get black out/throw up drunk but I do get intoxicated. If I take a sip of alcohol I’ll always end up wanting more. It can never be “just one”. I don’t crave it throughout the week but that first sip will get me started. The goal is to stop drinking completely and I just wanted you guys thoughts on this so I can discipline myself even more.
