A positive expression! Note to self,  make sure this patient gets added to the therapy animal rotation.

"Boba, are you ready to use Healing Bell?"

Boba shakes her neck-- while very carefully keeping her head still-- and rings the bell around her neck. 

It creates a soothing sensation that quickly stops, replaced by the feeling of being on no drugs at all. 

aaaaaaaaaaaaaaaaaaaaand the patient is immediately comatose again. 

... why would he ever think it would be that easy. Are his vitals still alright? Maybe, if they're both lucky, he's just really, really tired. 

"Thank you, Nurse Joy."

"Come along now, Boba."

:( human is asleep and other humans are worried, and this means no pets for Boba :(

His pulse is over 120 and he keeps twitching and the hairs all over his body are standing up and tears are leaking from his eyes!

No, tachycardia is not allowed. Practice in a busy emergency department, followed by slightly less practice in Milliways, means he can push anti-tachycardia drugs with one hand while bringing up UpToDate with the other. 

Mm, yep, that's Class J withdrawal. 

Why would he have ever expected anything else? 

Does UpToDate have any opinions about treatment other than "make sure patient's heart does not explode?"

It should be ramped down over a period of a week, standard Earth time.

... which is not a thing he can do with an implant in his patient he can't take out, and magical creature as his only method of detoxing.

Thank you, UpToDate, you have been very helpful. 

Time for as much supportive care he can throw at the situation by himself!
