The feeling is fantastic, nothing like weed or booze. You feel relaxed and warm in the sense that you want to be around people and talk to people. Like it fills you with love for humanity (I wanted to call my mother and tell her I loved her and so on.) BUT it makes you hyper aware of emotions so be sure your environment is relaxed if you're inexperienced. As you come down you will then start to wrestle with your own buried emotions which can really be a roller coaster. However, as long as the environment is relaxed you will feel safe and be able to handle them.
The trick is go slow for your first time, take a little and see how you feel as it take 30-45 min to kick in (for me 45 min like clock work almost.) Make sure you are in a good mental state. Had a bad week or something really bothering you? Not a good state. Don't trip. Make sure the environment feels safe and relaxed.
