This is a very common issue and one that can be successfully treated with hypnotherapy. It does not matter how small or insignificant your habit is, it is probably causing you a lot of stress and anxiety and often frustration that you just can't stop doing it. It could be that you keep drinking excessively or are unable to stop biting your nails. It maybe that your habit is a way of coping to deal with feelings of stress or anxiety. The addiction to a habit can often be a result of a false belief about that habit, such as thinking smoking will reduce your stress. With the use of strategic hypnotherapy, these false beliefs can be targeted at the non-conscious level so that new beliefs can be formed and the breaking of the habit will be easier.
