Are you more talkative on ecstasy?
Ecstasy generally ensures that you have more energy and that you feel more connected to the people around you. You may feel the need to talk a lot and tell your friends how much you love them.
But: those effects are not always the same and they are not the same for everyone. A high dose can make you introverted. You then feel less like communicating with others. If you are not feeling well mentally or if you are not enjoying yourself, you can also become more introverted. So watch your dosage.
