One possibility is to continue the twice a day for another week (I know it's a huge PITA), and then switch to doing once a day with about 150 cc instead of 100. Might be a good compromise. I don't know how anyone would be able to keep up with sub-cu twice daily on a long term basis. But once a day is way more do-able. I did once a day with Pearl for about 6 months, then was able to back down to 3xweek. After another 6 months it was 2xweek.
I think it would be good however for you to keep up the twice daily for another week if you can, since it obviously seems to be helping her a lot.

Glad that maggie is enjoying herself so much and feeling well!
