When you have four or five negative assessments, make some substitutions on your tapes. Keep the affirmations that are on your tapes which seem most important to you and replace the ones with which you are feeling most comfortable. There is nothing sacred about these scripts. You should feel free to change them however you want to make them fit your needs better. Even the suggestion of making positive suggestions is open to being broken.
Many people succeed with very negative suggestions.
I have worked with hundreds of clients who have incorporated negative suggestions to help them stop smoking and drinking and to lose weight. Suggestions that cigarettes or fatty foods will make you nauseous do work for some people. Feel free to try it. However, if you find that you are not listening to your tapes it may be that you are reacting to the negativity of the suggestions on the tape. If so, record a new tape without the negative suggestions.
