I'm in the same boat, sort of. I got so enthralled with my panther enthusiastically hand feeding supers from my hand, I didn't notice how many I was giving him and he's been hooked ever since. Fortunately, he will eat other worms like hornworms, silk worms, and phoenix worms, so I do try to rotate those in whenever I can get my hands on them. When I get my next chameleon, I will definitely be limiting the use of super worms.
Only advice I can give you is what I'm doing and that's to just make sure you give your supers as good a gut load as you can, change it up once a week or so and make sure you're dusting them.
My guy's over a year old so I feed him every other day. Jann, do you think that's too much and I should space it out more? I notice that he doesn't finish his supers every day...sometimes 4-5 or so he'll take from the feeder cup.
