Thank you for the support, BikerMatt!
No need to apologize for not seeing this. I posted around 1 am my time and then woke up and got the scan 7 hours later, so that doesn't leave a lot of room for people to reply.
I agree, as far as scans go, the HIDA scan was definitely not too bad.
By fatty drink do you mean a milkshake? I think that sounds like a great idea. If your gonna be in pain, you might as well enjoy some part of the experience, right? (unless the drink was actually really really nasty. In that case, I take it back.)
