Big weight loss?

[aegillesp]

Simon has been sleeping on and off for the whole month of October and has barely eaten anything. I weighed him yesterday and he was 20g lighter than when he went into a semi-brumation. He is parasite free, gets baths once or twice a week but I always try to syringe feed him water, which he doesn't mind. When I tried to feed him calcium covered crickets, he had a hard time snatching them up. I refrigerate mine for 30 mins to an hour so they'll stop moving when I want to feed him, and he likes it too since they don't move, but he had a hard time even lapping one up. His temp inside his hide is usually about 85 degrees and his basking spot is about 90-100 degrees. Which he'll usually bask for a little bit after I feed him, but he'll only eat about once or twice a week. Refuses to eat his veggies too. This worries me, but how worried should I be? The 20g was since mid to end of september.
