What would happen if pro-inflammatories and pro-sympathetics were replaced with morphine?

Hi:

Let's say I suddenly develop a hypothetical medical condition that causes the cells in my body that normally-synthesize sympathetic-stimulants [such as catecholamines] and pro-inflammatory chemicals [such as histamine and cytokines] to instead synthesize morphine. Second, this medical condition eliminates any/all bodily mechanisms that specifically cause any psychological or psychologically dependence of, addiction to, or tolerance of morphine. Third, this medical condition eliminates any/all bodily mechanisms specifically responsible for withdrawal of morphine. Finally, this medical condition magically prevents there from being any toxic amounts of morphine in any part of the body and also prevents any emergency-causing overdose of morphine.

With this medical condition, morphine-overdose is possible but not to the point where it would lead to any medical emergency.

Why symptoms would I experience if I were to develop this condition?


Thanks,

GX
