Does opiate withdrawal cause excessive urination? trying to wean down my pain meds and even a small drink of water makes me urinate alot.

No: Hi,Opiate withdrawal is known to cause restlessness,watery eyes,runny nose nausea,sweating,muscle aches among other symptoms,especially if taken for a long time &stopped suddenly.You are doing the right thing by GRADUALLY weaning yourself.To my knowledge,excessive urination is not due to opiate withdrawal.Good luck.

Opiate wwithdrawal: as a rule opiate withdrawal does no cause increased urination usually it is the opposite due to the vomiting and diarrhea
