Well, unfortunately YOU can't have her Baker Act'd. It takes the police, medical doctor request. psychiatrist or psychologist to do that. Why not call social services in your County and seek out someone who can give you good advice. While she may have played the role of mother to you, unless you carry the Durable Power of Attorney, you may need to have one of the step children do the investigating and requesting from social services. If you do carry the attorney in fact status, then you can start the ball rolling. In any event, it isn't a quick easy process if she stays in her home (as opposed to standing drunk on top of a building's overlook.) See what support you receive from her MD, and go from there.

There comes a time, in the care and feeding of elder relatives, that we have to put aside the emotional and do what we would encourage a friend to do in the same situation. I know that even in her more lucid times, if there are any, she might agree to stop drinking etc... but do nothing about it. Counseling can help her make her own decisions. An antidepressant might help her because she might be self medicating her depression with the alcohol (or trying to.)

Give her first option to follow through with your ideas for help. If that doesn't work, then have a family intervention. Make sure YOU ALL meet first and be sure you all agree on the process/steps. This will go farther with a doctor when you request she be Baker'd, imo.

If you wish to be very involved, then do the background work on making your concerns to her MD known, then the next time she gets out of hand, call the police and inform them you want her Baker Act'd. (For those of you who don't know, in Florida when someone is confined to a mental ward against their will, they are Baker Act'd. It's only for 72 hours during which time a psychiatrist will evaluate them to determine if they need to stay longer.) Remember, once she detoxes in lock up she might be quite fine, and they will have to let her out. So the long term plans seem best to try first, imo. Good wishes.
