A diet largely consisting of squid doesn't do much for the state of your digestive system or your breath, you really don't want to be breathed on by an elephant seal. Most of the time pods are quite fairly restful places in a constant snoring and guttural grumbling sort of way, but every now and then one of the inner most seals decides it wants to go to sea.
I have never had the severe symptoms you describe after a cleaning, that's quite a reaction, but have felt very tired. I chalked it up to emotional exhaustion as I hate having my teeth cleaned. I agree with Wayne Mikie, it feels good to see your name. Hope you are feeling better.
Teeth cleanings are sometimes dreaded. Between the prodding, strange noises, and occasional jaw discomfort, itâs easy to understand the apprehension. But the truth is: For most people, a teeth cleaning is simple and painless.
