You intended those instructions for the weekend only (when she was out of 0871).

Also, I believe she bought the 16oz bottle so she should be good even with the 10ml sample.

If not, Mary Jo, I still have an extra 2oz bottle of 0871 if you need it. I am leaving for VA Saturday morning so you would need to let me know today.
