I had a PET scan yesterday, think it’s at least my second and maybe my third. I get the consultant to do me a sedative as I am claustrophobic  & that helped. But after 6 hours of fasting, feeling a bit woozy from the sedative, you just want to get home. But I was stunned to find an e-mail from them asking for feedback, they are a private company, so maybe a bit over zealous. But I really think this is out of order, when you’re worried about what the results might be??
