It does seem kind of weird that they didn't seem to take into account the considerable amount of caffeine you'd had. Combine that and talking with a new T? I'd've probably been going a mile a minute too(!)
Though... like you said, she asked some questions and you hadn't been sleeping and had a lot of energy before the caffeine thing, so...
Maybe it was some mania starting? There's nothing wrong with having some energy. Maybe they're just erring on the side of caution?

Go ahead and check in with them, maybe your Pdoc will be agreeable to lower the dose back and keep an eye on it. Certainly worth asking. (Besides, then you don't have to worry about self-adjusting. )
