I suppose this depends on past experience of your own sensations. Are you usually able to tell the difference. Some people know, some people ignore, and some people really don't always know. Sometimes I can have major symptoms I don't even think about until my husband mentions it. Like I won't realize how fast I'm talking, or how giddy I am over silly things, I won't realize that things have been put into overdrive and the good feelings kinda make me want to doubt other perceptions. I've told my husband before, no no I'm just happy and come to realize down the line that it was more than that. I usually try to listen to my husband's words when he tells me I'm acting strange. Though many times I hate making all of the euphoria go away. I've learned though from experience, as happy as you feel when it's good is exactly how bad or worse you will feel if this is an episode and you land in depression.

However, if this is a new doctor, you usually know your body, and you aren't exhibiting any things that anyone else thinks is odd then you may very well be justified in thinking they're wrong. Keep it noted though, just in case.
