Hiya

Mine was exploratory too but I ended up taking almost a week, as I reacted to the GA.

You may need a little more recovery time if you're having surgery.

On the other hand, plenty of people have been back up and about in a couple of days.

If possible, could you arrange for a colleague to be a 'back-up' for you in the Saturday, just in case?

Good luck, hope everything goes well and you have a speedy recovery.
