Happiness about a new relationship has always led to hypomania in me (personally). Of course, there's that natural happiness that seems to mimic hypomania, but mine was way over the top. It can go either way.

I'll barely know the person yet and do things that are even more exciting: planning trips way too soon, spending more money. These are my personal triggers, but I guess what I am trying to convey is that it is important to just be aware of your own triggers. Change can bring on hypomania in some of us. Like I said, it might be normal excitement, but just make sure to tell your pdoc of any concerns. Make sure to get enough sleep and take care of yourself. You have insight, so that's a good thing.
