The city of London is quite a demanding place to live, work and socialise in and if you want to succeed you are going to have to right on top of your game. However, if you suffer from bad breath, you may as well give up from the beginning, because this condition is a social and working no-no; when you know you have it, you have to go to war on it in order to beat it. The first thing you might like to look at is your oral hygiene and your lifestyle- and then change to improve them. Get down to your dentists and once you have been checked for things like disease and decay in your gums and teeth, then sit down and discuss the problem and how you can do things better at home to conquer this problem. If you work hard, get yourself a list of things to do and tick them off as you go along, you can get over the condition in a few weeks and be putting yourself about again with confidence, but you do have to make a determined effort.
