If she seems happy enough, is eating well, maintaining her weight, weeing and pooing, doesn't seem stressed by it all - she's coping. The medication may take a few weeks to have any real effect. I used to keep a diary of symptoms & severity, so I could compare it week by week. It was really useful to keep me going when I had rabbits with really bad cases of EC. One rabbit took about 6 months before she was back on her feet and fully mobile again, but she was gradually improving week on week (most weeks, anyway). Anyone who didn't know would not have been able to tell how bad she had been (head fixed round to her shoulder, unable to stand, being hand fed for months). It is a roller coaster ride, so there will be some downs as well as a gradual improvement.
