Hello- My sister Ranae, has mental illness. She is on 3 medications for her mental illness, They all 3 say not to take with alcohol. She insists that she's fine. She's consumed Alcohol for over 20 years and I'm really worried for her Brain, liver and heart. She is drinking 3 to 4 glasses of whiskey with freska everynight. Lately she's been having some tremors, fainted, and hasn't felt well. I told her she shouldn't be drinking alcohol with her medications, but she says she's fine. I think she's in denial. What would you suggest?
