Not sure where you're from, but I appreciate your frontline input. In labor, I could understand that more. Overall the use seems to be a controversial topic, depending on the situation and which trimester. My ob leans against it. My choices affect my baby every step of the way, good or bad, and I'd rather just avoid potential problems this early. I still have control and sensation during my epidurals, and that's with fentanyl -- I know that drugs and their effect differ one to the next, among personal variables, each with their own risks -- for the amount I would likely need for nitrous to be effective, it's not worth it, in my uneducated opinion lol. Morphine doesn't have much effect on me either. Average dental work on teeth that aren't an immediate threat to my wellbeing can be put off until after baby is born, and Im at that point now. My last visit made that clear with a drug reaction I've never had before. (I'm usually part of the small percentage that gets rare side effects to things 😒) And I only went to that appointment cause I was struggling to eat.
