Hi cashart. I can relate to excitement being a trigger for hypomania/mania. It certainly has been for me in the past, too. Any kind of stress can trigger it for me, and so often people label stress in just negative terms. Highly pleasant excitement is stress, of a sort.

I agree that it would be best to nip this by the bud asap. Can you take some kind of "as needed" medication? Or if you don't have one, I agree with others that a call to your psychiatrist is highly recommended. Mania can definitely ruin vacations. I know. Believe me! The last time my husband and I traveled to Europe I became full blown manic. It got so bad that my husband was literally crying on the plane on our way home.

It is very good that you have some insight into what is happening. It is good that you realize that obsessive infatuations are symptoms of your growing manias. Wasn't it you that a while back had a major infatuation (to an extreme degree) with Rod Steward? During that period, I believe you were hypomanic or even manic. If that was you, I recall it seeming scary. I was quite concerned. Perhaps this type of symptom is a common one for you?
