How to help my mom sleep?

Hello everyone. Hope you’re all doing well. I’m currently stressing thinking about what I can do to help my mom sleep. She has struggled with sleep for as long as I can remember. She is the lightest sleeper I know and once she’s up, she can’t fall back to sleep. She recently turned to alcohol to help her but it’s becoming a problem. She’s been needing to drink an entire wine bottle to help her sleep and now that isn’t working for her anymore. I’m afraid that she’ll turn to hard liquor or just in general become an alcoholic.

She’s very stubborn though, she doesn’t hear my advice about sleeping pills, she doesn’t believe she has a high tolerance for alcohol even though she needs to drink an entire bottle every night. I tell her to avoid her after work naps because that could also be a factor to why she can’t fall sleep at night but she doesn’t listen. She just woke up an hour ago and went to the store to get another bottle….. it’s 4am…. I don’t know what to do.. I hate seeing her tired all of the time.
