Yes, they put my Mom on somthing similar -- it created delusional thoughts, crazy dreams. She was telling us that she had a bed mate, but she was okay with it and that she had bought a car for our Dad (he passed two years ago) and that she wasn't sure how to get it up to where she was in the mountains. So she went from living in the moment and forgetting things to downright delusional. We took her off it right away.
And, as a side note, I wouldn't email the person in the other post, or even get the link. I think it's a spammer.
