Bless you heart ren, I can imagine how you feel. The compassion you have in wanting to help the elderly and make them happy, yet the conflict in having to give them these medications.
I remember when I used to visit nursing homes and assisted living facilities on a volunteer basis and the helpless feeling I had with regard to not being able to point them to natural healing. I was told in no uncertain terms, that if I spoke of natural healing, I would no longer be welcome. So I kept quiet.
Sounds to me like you have a dream, and to you I say......... "Follow that dream." A holistic day care for the elderly sounds wonderful and that could be the beginning of many new doors opening.
