Mother refusing medication

My mom has been suffering from schizoaffective disorder my entire life. I will not lie that she does have a mild case as she is not a harm to herself or others. She suffers from mood swings and paranoia. Most paranoid thoughts surround money. She thinks she won the lottery for 10 billion and people at the gas station stole her ticket, etc. We have had her committed a handful of times but in the past 2-3 years she’s been committed twice and each time has only taken her medicine for a few months and then stops. Are they any recommendations on how to keep her on the medicine? We tried the shot last time and it worked so well but it is monthly and she didn’t go back to the doctors for it. Are there any other ways to keep her episodes and paranoid thoughts at bay without medicine? I am open to any and all options to help her live a happier life!
