This could also be a hunger strike. Agree that parasites should be ruled out and it’s just good practice to test. Here are some good sources to read about causes for hunger strikes:

I let them turn into moths! It’s fun to watch them and the moths are nutritious and imo the bodies are a little smaller than the grubs, but obviously the wings are there so they’re still a pretty big bug.
I use a bulb with a dimmer, that way you can adjust it if it gets too hot. I got mine from Amazon, it looks like a light fixture with a little knob on the wire. I also recommend an IR temperature gun to monitor the temps, they’re pretty cheap.
Very important mention—- you NEED a thermostat to monitor any kind of heating element that makes contact with your gecko (eg. heated rock, heat mat) because they will cause burns. They can be dangerous if not monitored.
Mine tends to do these impossibly large “yawns” when he’s about to shed and it freaks me out every time. It looks his jaw will unhinge or get stuck, haha.
Additionally regarding the dripper- Neptune demonstrated a method of poking a pinprick hole in the bottom of a washed out gallon milk jug or equivalent, it gives a steady drip without paying for the big dripper from the store.
I did the same thing! I moved away from the Reddit forum for pets because people are so negative, there is a huge “vent-hole” moderator who yells at people and drives them away. And the water cups never worked for me, my chameleon was dehydrated.
OP, there is a great podcast by Chameleon...
