The context of what was going on with your snake fit what I said at the time. Things are much different for your animal now.

My guess is that your snake is actually healthy for the first time since you've had him ... remember, he was shipped, ate, regurged, traveled to the vets office, was medicated a couple of times, then started eating properly, got back up to good weight, and finally used his bowels in a good way for the very first time .... now he's acting like a ball python during it's first couple of days in a new cage .... sounds abouit right to me.

All that said, if you really have a concern, I urge you to see a vet ... NO ONE can tell you if your snake is either sick or healthy over the internet.
