It could be the adrenaline given during surgery that causes an inital awake and hyped up feeling. Then when it is out of the system after a couple of days a crash can occur.
I've asked for no adrenaline for my up-coming surgery for that reason. I do really badly after surgery if it is used.
Hope you continue to feel well PasstheBrandy!
Morning.....I used to feel wide awake after my surgery.Had several ops due to implants failing etc.When I got home following surgery I would be full of beans.I realised I had spent most of the day in bed,and fast asleep!
take care....💞💓💞
