Welcome (((Alton)))
I think only your Mom knows whether she's an alchoholic.
What we loved ones find though is that something brings us here... fear, hopelessness, rage, all different emotions.
I doubt that you're just asking for heck of it, so chances are your Mom's drinking has has had a negative impact on your life.
Does it really matter then how we label it?
My sister is an alchoholic (my term), as is my Dad, although Dad no longer drinks because he can't...he's under someone elses care (ironically my sister)
I've given up lecturing to the sis...I can't control her or her drinking. She too "bounces" up in the morning...somewhere in her head she's convinced herself that if she isn't having the typical hangover, she doesn't have a problem. But this is the same gal that can't put a sentence together by 9pm.
Stick around and stay a spell, read around.
Regardless of where things land with your Mom, you can focus on you, and prevent getting dragged in as things progress.
And they may well progress...addiction is a progressive desease.
Glad you've joined us
