He'll get some regular wet food tonight and we'll see if he has a normal night. There's only been one real incident since the day he went to the vet, when he got into some dry food I didn't realize Sam hadn't finished. But that was the very next day, and he wasn't supposed to have any of his regular food yet.
My back is already doing so much better. I wish a doctor would have recommended yoga as an alternative to PT years ago. It's just so much more effective for me. And less boring. And quicker. And easier. I think I'll finish this week out with yoga and do a Sunday morning walk. Assuming I feel as good Sunday morning as I do right now.
