It’s odd when this was me posting about having one, and then suddenly you have had it, and can tell others.
I had sedation, to be honest it must have done something but i didn’t feel like it affected me that much. At one point i had a little discomfort as they were doing the procedure, and I told them, and they gave me a bit more sedation, and that was it, barely felt anything really, and wasn’t too long and they said it was done, I was surprised.
I was worried about the blowing with air that I had heard about that they have to do, but it was fine.
If you do have sedation then obviously as you know you will need to be chaperoned, and you will need to rest afterwards.
If you don’t, still after all the prep etc, probably won’t get much sleep the night before, then up to get to hospital etc, plus I know you say it’s a morning one, but that is your booking time, that does not mean you will be seen at that time.
So bare that in mind too, you really should just take the day off, unless there is some real need for you to make sure you are back at work.
