My mother has moderate Alzheimer's. This oil is letting her SLEEP!!! She only woke up once in the middle of the night, after the first day of taking it, as apposed to 5 or more times. Its only been 4 days and she's sleeping through the night. I only gave it to her once a day instead of 4 times a day, which is the suggested use. Today I gave her a second dose and she remembered the date of her son's Birthday. With supplements, it normally takes 1 to 3 months to see results. So, I can't understand why I'm seeing any results, so fast. She's also taking Fish oil. Maybe it's all the omega 3 both supplements have. I don't know, I'm not a scientist, I'm just a daughter that's happy to see her mother finally getting a good night's sleep after suffering without (barely any) sleep for 4 years.-- Update: about 4 months later -- Never mind - it only worked for a week. My mother is still not sleeping well. Sorry folks, I was kind of hoping this product could help her. Real sleeping pills are extremely dangerous to Alzheimer's patients. Oh well, back to the drawing board.
