Yeah I'd have to echo the others. I would also chew in social situations. I think the only reason we can't have it is because it may induce cravings or make us feel hungry. It doesn't bother me so happy days.
Just be warned though that it does make the stomach think there is food coming and sets the gastric juices off which can then start eating the stomach lining when food doesn't arrive adn cause an ulcer. I know stomach lining may weigh a few pounds and there maybe the temptation to give it a try lol. But I wouldn't go overboard.
