Being drunk can make you feel overconfident. When your inhibitions are lowered, you might feel like you can’t fail. This might make you want to show everyone your dance moves or a special talent. Similarly, it might make you feel confident enough to ask someone out or confess your feelings.  As an example, you might decide to dance when you normally don’t or you may show off your karaoke skills even though you’re usually too shy. It's okay to have fun, but don't risk your safety. Check in with your friends to make sure you're not putting your safety in jeopardy. For instance, doing karaoke may be fun and safe, but dancing on a bar might be dangerous if you're drunk. Consider if you’re feeling extremely happy, excited, or depressed. Similarly, watch for signs of mood swings, like feeling happy 1 minute and sad the next. It’s common to feel emotional when you’re drunk.  For instance, you might be dancing with your friends thinking this is the best night of your life, then suddenly crying about something that happened last year. Turn off your cell phone or ask a friend to hold onto it if you're feeling tempted to text people about things that happened in the past. For instance, if you're considering confronting your ex, give your phone to your friend. Alcohol lowers your inhibitions, so you feel bolder than usual. This often makes you friendlier than normal, so may feel more comfortable talking to people you just met. Consider if you’re sharing secrets with people you don’t know or becoming instant friends with the people around you.  For instance, you might catch yourself telling a stranger about your family. Try to stick close to your friends or someone you know so that you stay safe. When you’re drunk, it’s normal to talk louder than usual, though you likely won’t notice this. However, people around you may ask you to lower your voice or might cover their ears. Similarly, it’s hard to speak clearly when you’re drunk, so people might ask you to repeat yourself or may respond with “what?”  People might say, “You’re being too loud,” “Lower your voice,” or “What are you trying to say?” If people are complaining that you're being loud, try communicating in a whisper until you feel less drunk.
