Skip the fruit and veggies for a week. Feed her whole rodents only, and only those with a complete skeleton. Coat those rodents with a calcium supplement that does not contain phosphorous but does have D3. Get her a mercury vapor bulb of a good name (ZooMed, ExoTerra, MegaRay) and place it so that her basking spot attains a temp of 110-115. Her tremors should stop. If you can get her outside, get her some natural sun for at least an hour. After a week, resume the diet you were feeding her, and supplement any food that does not have bones (ground turkey, bugs, fruit, etc).
