I'm so glad to hear that she's up to 200 grams finally, that's fantastic news. I can tell you that I myself did not realize just how long it takes sometimes to get back to normal, as I had never had a "sick" dragon in 15 years of owning them, my first one I had from a month old to almost 13 years old, and currently I have my girl who I got at a month old and who is just turning a year old now, and my boy who I got at 4 weeks old who is just turning 7 months old now, and none of them were ever sick, not once, until about 2 months ago. Dee Dee, my now 7-month old male, suddenly stopped eating about a month and a half to 2 months ago. He was prior to that a literal garbage disposal. He was becoming obese. He'd eat 20+ large BSFL, then as soon as I set his greens/veggies down he'd eat all of them, then he'd beg for a piece of banana (he would have eaten an entire banana had I let him). He just wouldn't stop eating...then one day he just stopped eating. At all. Nothing...
Long story short, my Certified Reptile Vet diagnosed Dee Dee with an "infestation" of Pinworms. I saw them in his poop, and I had to start feeding him by hand with an oral syringe daily. His eyes sunk in and he lost a huge amount of weight. It was awful, I thought I was losing him. After multiple rounds of Panacur, my CRV gave me a jar of Alfalfa Meal that was medicated with Panacur and Probiotics with Digestive Enzymes. I added the recommended amount of this Alfalfa Meal to one of his daily slurries about 2 weeks ago, and did that for 5 days, then gave him nothing but unflavored Pedialyte for 3 days, and BAM, he's eating normally like he did before he got sick, his follow-up fecal test was normal, and he's already put on 40 grams in a week or so...but man, that month and a half was torture for me, I cannot imagine one of my guys not eating for any longer than that like your guy. So thank God he's okay...
I guess the moral of the story is patience...easier said than done though when you love them so much...
