Evelyln, have you considered switching from the gum to the patches for a while? In some ways, the gum is very similar to cigarettes. You remain addicted to the nicotine, of course. But when you finish chewing a piece of gum and throw it away, you start to build build up a craving for nicotine just like when you finished a smoke. The craving continues to intensify and you are "jonesing" for a fix until you chew another piece of gum. When you do, you get a "hit" of nicotine and the a-a-a-a-h of relief. All of this reinforces a dependence on nicotine gum just the way it did for cigarettes.
With the patches, on the other hand, you get a slow steady stream of nicotine. It's enough to minimize the withdrawal symptoms but not the periodic "hit" of the gum. Also, you eliminate the stimulus-response behaviors associated with gum.
If you are very sensitive to nicotine and really worried about withdrawal symptoms, I suggest that you switch to the patches for a few weeks or a month and then taper off them.
[by the way, if you find yourself having "amazing technicolor dreams" while on the patches, remove them at bed time and put a new one on in the morning. I got some amazing dreams when wearing the patches at night and that disturbed my sleep.]
