Hi Al
Welcome to SR.
I started my drinking career in much the same way - I outdrank most of the things I started drinking for.
I can;t say whether you're an alcoholic or not - but if you think your drinking is a problem, it probably is.
There's many self diagnostic tests available. This is one.

It's not meant to be definitive but it may help you decide where you are.
You'll find a lot of support here Al - keep posting
