Baby suddenly not eating

[Boundangel]

I need your help figuring out if something is up with our baby. This is Draco and he is giving me major anxiety! This weekend he decided that he wasn't interested in eating. The next day we wake up to his legs shedding. The shedding stopped but he is still not interested in his food. The first few days he ate about 4 dubia (3/8") each day. Then it was just 1 and then none. Yesterday I picked up some BSFL and he gobbled up 19! Now today he won't touch either the dubia or BSFL.

We've had him for about 6 weeks. He has never been a huge eater but this is the first time he is straight up refusing food. He ate yesterday (and has been drinking water), is still pooping every day, still is active and alert, and hasn't lost any weight (8" and 18grams). He did just go through a huge growth spurt (1.5 inches and 5grams in the last 2 1/2 weeks but has only his legs have shed in this time frame) so I'm wondering if he is just taking a break for a few days. I have no idea what is going on.

What UVB do you have? You need reptisun 10.0 fluorescent tube or Arcadia 12%.
How far is the UVB from the basking spot?
What are you temperatures? Is the basking spot around 105-110F?
Is he hydrated? Move water in a dish with your finger to show him and/or drip water on his nose with a dropper until you can get him to take a lick.

We use a reptisun 10.0 T5 that is about 7 inches from the basking spot. His basking temps are about 108F and his cool side is around 84F (we live in Southern California and are still having hot temps). He has been drinking water when we drop it on his nose.

We took him to the vet last night (specializing in reptiles) and we came home with several meds. We went over our tank set up, diet, and supplements with the vet who said that it sounded like we were doing things right. They said that he was slightly dehydrated and gave him fluids under the skin while we were there. They also said soak him twice a day for at least 10 minutes. They did take x-rays. There was no impaction just lots of poop. They are having us give him lactulose syrup twice a day for about two weeks. They also said that his bones seem a bit weak so we are giving liquid calcium once a day for now on top of the calcium dusted on his food. They said that low calcium might be why he was having problems with his head shedding and why he hasn't had a full shed in at least a month. As for his lack of appetite, they prescribed Flagyl once a day.

This morning he did eat 3 bsfl (First time eating since Wednesday). I gave him a soak a few hours later and he tolerated it for almost 10 minutes. I'm not sure if I am going to force him to do this twice a day since it is unlikely that it will help him hydrate. He did drink water dripped onto his nose while he was soaking. He still seems to have energy and is alert. I'm nervous having to give him so many meds but am willing to do whatever I need to do.

Is there anything else we can do to increase his appetite or help him heal up? Attached are the pictures of his x-ray and a pic of my boy with his dragon.
