Of course, we can't exclude any of these diagnoses, but considering the context, the most likely diagnosis is opioid withdrawal.

All of the usual symptoms of opioid withdrawal are present (which include mydriasis, tremors, nausea, and "psychiatric" signs, such as anxiety, depressive disorder, insomnia, irritability, and panic attacks). Lab tests sometimes show hemoconcentration with hyperleukocytosis and hyperglycemia. The symptoms of opioid withdrawal can start within hours of the last dose and generally last a week.
