Does anyone else find it easier to laugh, and laugh exceptionally longer?

Been on E for about 4 months now. One of the strangest emotional changes I've felt besides the usual ones is laughing extremely hard to tears nearly every day and multiple times a day. Not just laughing, uncontrollable vocal laughs with tears almost instantly. I used to laugh like this once every couple months maybe. But ive noticed it 4 times in just the last few days alone.

Is this common with others, does it come from the hormone changes and is it anything to be concerned about? Or is this unbridled joy and laughter just something I should embrace and stop worrying about?
